Answer:
x=2 and x=-2
Step-by-step explanation:
f(x)=(x-9)(x+7)
------------
(x^2-4)
Vertical asymptotes concerns the bottom factors after simplification.
This cannot be simplified any further because x^2-4=(x-2)(x+2)
which means it has no common factors with the numerator (the top part of fraction)
So we will consider when both factors are 0.
x-2=0 when x=2
x+2=0 when x=-2
So the VA (Vertical asymptotes) are x=2 and x=-2
You must actually write x=2 and x=-2
Do not put just 2 and -2
