Thread: Graph of a rational function

- You have a vertical asymptote at x=-3 and one at x=3.
- An even function is symmetric with respect to y-axis.
- You probably know how to plot points.
- There is an asymptote at x = 2 the function may or may not cross it but we must see that y goes to 2 as x goes to infinity.
- On the left of x = 3 asymptote, y goes to infinity and on the left it comes from -infinity.
- Because of symmetry, it is the opposite for x = -3 asymptote.
