Idedntify all asymptotes - help please?

Question

Identify all asymptotes, G{x}= x^2-9 / x^2-4



1. Vertical asymptote, x = 2; Slant asymptote, y = x; Horizontal Asymptote, y = 0

2.Vertical asymptote, x = 2, -2; Slant asymptote, None; Horizontal Asymptote, y = 0

3. Vertical asymptote, x = 2, -2; Slant asymptote, none; Horizontal Asymptote, y = 1

4. Vertical asymptote, x = 2, -2; Slant asymptote, y = 1; Horizontal Asymptote, y = 9/4

Answer 1

Answer : 3

Vertical asymptotes are where the denominator cannot equal to 2
Both x= 2 and -2 will create a asymptote.
I used calculus for the horizontal asymptote which is =1
There are no slant asymptotes.

Answer 2

You meant G(x)= (x^2-9) /( x^2-4), right?

3 is the correct choice.
