First thing we need to do here is simplify this equation.
00:02
So we have a bunch of fractions inside of our fractions.
00:05
We need to get rid of the fraction.
00:06
So we're going to multiply by a common denominator of x both top and bottom.
00:11
So we get when we distribute, we get x squared minus one all over, distribute the bottom, x squared plus one.
00:20
And that is our new function of x.
00:23
Now we need to graph this.
00:27
Easiest way to graph it is to make a set of, make a, make a, table.
00:37
So i'm going to choose a negative number, a zero, and a positive number.
00:41
So if i plug negative one into my equation, i get negative one squared, which is one.
00:48
One, one minus one is zero.
00:50
All over on the bottom, i would get two.
00:52
So zero divided by two is zero.
01:04
So i'm going to graph that number.
01:08
If i plug zero in, i get negative one over one, which is negative one.
01:17
If i plug one in, i'm going to get the same thing i got for the first one...
