Answer to Problem 9E
There is a vertical asymptote at x =1.
There is a vertical asymptote at x =-1.
There is a horizontal asymptotes y =3.
Explanation of Solution
Given information: Given function
Calculation:
From top two tables:
So, there is a vertical asymptote at x =1.
Since
From the bottom two tables:
