Question

State the vertical asymptote of the rational function. f(x) = ((x-9)(x+2))/(x^2 -4)

Answer 1

Well, you want to factor out the bottom and see what does or does not cancel. If a term on the bottom cancels, then that factor is only solving for a hole. So you will factor the bottom, see which term DOES NOT cancel, and solve x for x for that value.

Answer 2

thank you very much (:
