This question is about football matches between teams. A record of games played between teams is stored in a graph G. Each edge in the graph corresponds to a match between a pair of teams.
For example, if there is an edge between vertices 3 and 6 then Team. Solve the system of equations. Then match each equation with it's graph. Im doing math homework and having some trouble. Its called "Graphing equations", and this one is hard. What do I do first to be able to match it? Please help a.

Graph the linear equation. I need coordinates, but don't think they match up to my choices. I would appreciate some feed back. For the data in the table.
A hockey match is played from 3 p. A man arrives late for the match. What is the probability that he misses the only goal of the match which is scored at the 20th minute of the match? In this set of eight problems, we have to match each equation with the correct description of its graph. However, these are test corrections I'm doing and I do not have the previous multiple choice answers so I can deduct from it, but can someone help me?
I'm unsure how to solve this Match the equation with its graph. But im not sure how to figure it out. Find a linear equation whose graph is the straight line with the given property.

Match the root with its meaning. Match the items in the left column to the items in the right column. I'm trying to graph a set of points with data, and I have been given the equation for the best fit line, but when I graph it, the line doesn't match up with the data. It's either too steep or too low. I think it has to do with my intervals for the x and y.Calculus, Applications and Theory. Recommend Documents.

But with a solid understanding of the concepts, and a few algebraic techniques in your toolbox, it is not too difficult to locate the vertical asymptotes of a function. There are three types of asymptote: horiztonal, vertical, and oblique. This article focuses on the vertical asymptotes. Horiztonal asymptotes are discussed elsewhere, and oblique asymptotes are rare to see on the AP Exam For more information about oblique, or slant asymptotes, see this article and this helpful video.
Imagine that you are flying in an airplane and up ahead you see a huge mountain. Now imagine that mountain is vertical and infinitely high.
Then you might fly upwards forever to avoid hitting it, and still never get over the mountain! A function may have any number of vertical asymptotes, or none at all. Some functions even have infinitely many VAs. Because the definition involves variables approaching fixed values, it should come as no shock that limits must be involved somehow. The precise definition for a vertical asymptote goes as follows. There are two main ways to find vertical asymptotes for problems on the AP Calculus AB examgraphically from the graph itself and analytically from the equation for a function.
If a graph is given, then look for any breaks in the graph. It helps to sketch a vertical line at the x -value where you think the asymptote should be see the graph shown above.
Note, if part of the graph actually touches your vertical line, then that line is not an asymptote after all. If you need to find vertical asymptotes on the AP Exam, you will most likely not be given the graph. Ask yourself, where does this function have an infinite limit?
Factor both the numerator top and denominator bottom. This is very important because if any factors end up canceling, then they would not contribute any vertical asymptotes. Once your rational function is completely reduced, look at the factors in the denominator.
Note how the sign seems to be opposite both times just like solving a factored polynomial that has been set equal to zero. Since the factor x — 5 canceled, it does not contribute to the final answer. The method of factoring only applies to rational functions. However, many other types of functions have vertical asymptotes. Perhaps the most important examples are the trigonometric functions. Out of the six standard trig functions, four of them have vertical asymptotes: tan xcot xsec xand csc x.Vertical Horizontal Slant Examples.
Vertical asymptotes are vertical lines which correspond to the zeroes of the denominator of a rational function. They can also arise in other contexts, such as logarithms, but you'll almost certainly first encounter asymptotes in the context of rationals. This is a rational function. More to the point, this is a fraction. Can we have a zero in the denominator of a fraction? So if I set the denominator of the above fraction equal to zero and solve, this will tell me the values that x can not be:.
So x cannot be 6 or —1because then I'd be dividing by zero. This avoidance occurred because x cannot be equal to either —1 or 6. In other words, the fact that the function's domain is restricted is reflected in the function's graph.
We draw the vertical asymptotes as dashed lines to remind us not to graph there, like this:. It's alright that the graph appears to climb right up the sides of the asymptote on the left.
This is common. As long as you don't draw the graph crossing the vertical asymptote, you'll be fine. In fact, this "crawling up the side" aspect is another part of the definition of a vertical asymptote. We'll later see an example of where a zero in the denominator doesn't lead to the graph climbing up or down the side of a vertical line. But for now, and in most cases, zeroes of the denominator will lead to vertical dashed lines and graphs that skinny up as close as you please to those vertical lines.
Let's do some practice with this relationship between the domain of the function and its vertical asymptotes. The domain is the set of all x -values that I'm allowed to use. The only values that could be disallowed are those that give me a zero in the denominator. So I'll set the denominator equal to zero and solve. Note that the domain and vertical asymptotes are "opposites". The vertical asymptotes are at —4 and 2and the domain is everywhere but —4 and 2.
This relationship always holds true. To find the domain and vertical asymptotes, I'll set the denominator equal to zero and solve. The solutions will be the values that are not allowed in the domain, and will also be the vertical asymptotes. That doesn't solve! So there are no zeroes in the denominator. Since there are no zeroes in the denominator, then there are no forbidden x -values, and the domain is "all x ".
Also, since there are no values forbidden to the domain, there are no vertical asymptotes. Note again how the domain and vertical asymptotes were "opposites" of each other.When expressed on a graph, some functions are continuous from negative infinity to positive infinity. However, this is not always the case: other functions break off at a point of discontinuity, or turn off and never make it past a certain point on the graph.
Vertical and horizontal asymptotes are straight lines that define the value that a given function approaches if it does not extend to infinity in opposite directions. Finding asymptotes, whether those asymptotes are horizontal or vertical, is an easy task if you follow a few steps. To find a vertical asymptote, first write the function you wish to determine the asymptote of. Most likely, this function will be a rational function, where the variable x is included somewhere in the denominator.
As a rule, when the denominator of a rational function approaches zero, it has a vertical asymptote. Once you've written out your function, find the value of x that makes the denominator equal to zero. There may be more than one possible solution for more complex functions. Once you've found the x value of your function, take the limit of the function as x approaches the value you found from both directions.
For this example, as x approaches -2 from the left, y approaches negative infinity; when -2 is approached from the right, y approaches positive infinity. This means the graph of the function splits at the discontinuity, jumping from negative infinity to positive infinity.
If you're working with a more complex function that has more than one possible solution, you'll need to take the limit of each possible solution. Finally, write the equations of the function's vertical asymptotes by setting x equal to each of the values used in the limits. While horizontal asymptote rules may be slightly different than those of vertical asymptotes, the process of finding horizontal asymptotes is just as simple as finding vertical ones.
Begin by writing out your function. Horizontal asymptotes can be found in a wide variety of functions, but they will again most likely be found in rational functions. Take the limit of the function as x approaches infinity. In this example, the "1" can be ignored because it becomes insignificant as x approaches infinity because infinity minus 1 is still infinity. Use the solution of the limit to write your asymptote equation. If the solution is a fixed value, there is a horizontal asymptote, but if the solution is infinity, there is no horizontal asymptote.
If the solution is another function, there is an asymptote, but it is neither horizontal or vertical. When dealing with problems with trigonometric functions that have asymptotes, don't worry: finding asymptotes for these functions is as simple as following the same steps you use for finding the horizontal and vertical asymptotes of rational functions, using the various limits. However, when attempting this it is important to realize that trig functions are cyclical, and as a result may have many asymptotes.

Horizontal asymptotes occur most often when the function is a fraction where the top remains positive, but the bottom goes to infinity. When we go out to infinity on the x-axis, the top of the fraction remains 1, but the bottom gets bigger and bigger.
As a result, the entire fraction actually gets smaller, although it will not hit zero. As you can see in the above graph, the equation approaches zero eventually. Because the bottom will dominate the top, the fraction approaches zero as x gets closer to infinity. Now, examine what happens when x approaches infinity. Now our equation looks like this:. When x gets to infinity, y is getting really really close to 3. To find horizontal asymptotes, simply look to see what happens when x goes to infinity.
The second type of asymptote is the vertical asymptote, which is also a line that the graph approaches but does not intersect. Vertical asymptotes almost always occur because the denominator of a fraction has gone to 0, but the top hasn't. This is because the numerator is staying at 4, and the denominator is getting close to 0.
That means that the fraction itself is getting very big and negative. When x is exactly 2, the function does not exist because you cannot divide by 0.
Immediately after 2 it resumes at positive infinity, because the numerator is 4 and the denominator is again very tiny, but this time it is positive. To find vertical asymptotes, look for any circumstance that makes the denominator of a fraction equal zero. Those are the most likely candidates, at which point you can graph the function to check, or take the limit to see how the graph behaves as it approaches the possible asymptote. All of those vertical lines are really asymptotes, which brings up a good point.
Your calculator or computer will most likely draw asymptotes as black lines that look like the rest of the graph. This is because the computer wants to connect all the points, and it is not as smart as you. You must use your own judgement to recognize asymptotes when you see a computerized graph.

I Graphs and Models 3 Point of intersection: 1,1 Point of intersection: 5, 2 Points of intersection: 2, 2—1,5 Points of intersection: - 1, -22. Points of intersection: 0, 0- 1, - 11, 1 This problem can also be solved by using a graphing utility and finding the intersection of the graphs of C and R.
False; j:-axis symmetry means that if 1, -2 is on the graph, then 1, 2 is also on the graph. Section P. Therefore, three additional points are 0, 11, 1and 3, 1.
Therefore, three additional points are 0, 102, 4and 3, 1. Given a line L, you can use any two distinct points to calculate its slope. Since a line is straight, the ratio of the change in y-values to the change in jr-values will always be the same. See Section P. Therefore, the slope is undefined and there is no y-intercept. The lines do not appear perpendicular. The lines appear perpendicular. The lines are perpendicular because their slopes 1 and — 1 are negative reciprocals of each other.
You must use a square setting in order for perpendicular lines to appear perpendicular. The slope is
