At which values of x does the function F(x) have a vertical asymptote? Check all that apply,
F(x)
9
(x - 1)(x-8)

The values of x that makes f(x) have a valid asymptote are 1 and 8

Step-by-step explanation:

Given

Required

At what value does f(x) has a vertical asymptote

To solve this, we simply equate the denominator of f(x) to 0;

This is done as follows

This can be split to

Remove brackets

Make x the subject of formula in both cases

The values of x that makes f(x) have a valid asymptote are 1 and 8
