Question

At which value(s) of x does the graph of the function f(x) have a vertical asymptote?

Answer 1

E. x = 4

F. x = -2

Explanation:

Asymptotes occur when you have an undefined (a divide by 0 error). So x in the denominator can't equal zero. The 2 values that make the denominator zero are 4 and -2.
