Answer:
A.x+4
Step-by-step explanation:
We are given that a rational function which has a vertical asymptote at x=-4.
We have to find the term which appears in factored form in the denominator of the function.
We know that
To find the vertical asymptote of a rational function we will substitute the
denominator equal to zero.
Then, solve for x.
The value of x obtained are called vertical asymptotes.
By definition of vertical asymptote
x=-4
x+4=0
x+4 will be appears in factored form in the denominator of the function.
