Answer:

Explanation:
Since the roots are -4 and 5, we can write that as

Apply foil method to find our denominator.
We get

So that our denominator.
Since our denomiater gives us interger asymptote, our degree in our numerator must be 1 so the answer has to be a single interger or a single term.
Since our x intercepts is -2, we use

So our rational denomiater is
