- Shot: 2 Frame: D
- Duration: 0:10-0:19 Angle: Overhead Close-UpAudio 2: For today’s lesson, don’t forget you are going to need your calculator and some graphing paper. Any calculator will do the trick, but as always, a good calculator like the Ti-36x will make your life easier

- Duration: 0:20-0:40 Angle: Overhead Close-UpAudio 2: First of all, we check if we can factor. In fact, we can. This binomial is a difference of squares, so we will write two parentheses, and we will have x plus one, and x minus one.
- xx2-1x(x-1) (x+1)
- Duration: 0:41-0:56 Angle: Overhead Close-UpAudio 2: Now that we factored, we have to find the asymptotes. For the vertical asymptotes, we set the denominator equal to zero. Our answers in this case would be x equals negative one, and x equals one
- Vertical Asymptotes(x-1) (x+1) = 0x=1 , x=-1
- Duration: 0:57- 1:13 Angle: Overhead Close-UpAudio 2: For our third step, we find the horizontal asymptote. We take a look at this table right here. Because this degree is smaller than this one, the table says the asymptote will be y equals zero
