A
This is one of those questions that is hard to explain, because I don't know what you know. I'll start with the most obvious reason I know. At x = -1 the top and bottom of the function is 0/0. zero/zero can give indeterminate results and you must look for other ways of explaining what is going on. Here's another thought which is less reliable.
The fraction factors.
(x + 1)*(x - 1)
============
(x + 1)
The two common factors cancel and you are left with f(x) = x - 1
If you have a graphing calculation you can put this in as y = x - 1 and you see that it is a straight line.
Question B is much nicer
when you put x = 1 into the fraction, you get 0 /2 which gives you 0. That's much easier to handle because the answer is 0.
you are still graphing y = x - 1, but this time the graph is much more well behaved.
Answer:
Draw a graph which joins the points (100, 135) and (500, 375) and has a slope = 0.6
The ordered pairs are: (100, 135) and (500, 375)
The first number is the number of minutes of usage and the second number is the charge of the month.
The slope is: ( 375 -135) / (500 - 100) = 240/400 = 0.6

Step-by-step explanation:
If Victor drove away from his house he would have started at "0" on the graph. The more Victor drives, the farther from his house he would get and the more time he would have spent driving.
