Answer:
D. 81
Step-by-step explanation:
A zero of a function is a value of the variable that makes the function value zero. Here, the function is the product of two factors. The product can only be zero if one of the factors is zero.
x -81 = 0 ⇒ x = 81
x +4 = 0 ⇒ x = -4
Of the two values that are zeros of h(x), the one on the list of choices is x = 81.
