Question:

Write the function with a hole at {eq}x=4 {/eq}, a horizontal asymptote at {eq}y=2 {/eq}, and a vertical asymptote at {eq}x=-1 {/eq}

Graph of a Rational Function:

The rational function has a hole whenever the numerator and the denominator both evaluate to zero. It has a vertical asymptote where the denominator evaluates to zero but not the numerator. It has a horizontal asymptote when the degrees of the numerator and the denominator are the same.

Answer and Explanation:

First note that we are given that there is a hole at x=4, so the numerator and the denominator must evaluate to zero there. So we give a factor of x-4 ...
