Question

Find the vertical asymrtotes, if any, for the following;
f(x)=-3x^2/x^2+9x-22
The answer I have is x=2 & x=-11
How do you come up with 2????

Answer 1

The factors of x^2+9x-22 are (x+11)(x-2)
If either of these factors is 0, the denominator will be 0 and there will be a vertical asymptote.

Answer 2

so then I have it right with x=-11 & x=2

Answer 3

Yes.

Answer 4

ok thank you
