ANSWER


f(x) =x^3-6x^2-13x+42

Step-by-step explanation

The zeros of the cubic function is given as:

x=7,x=-3,x=2

This implies that, x-7,x+3,x-2 are factors of the given cubic polynomial function.

We can write the completely factored form as a function of x to get:


f(x) = (x - 7)(x + 3)(x - 2)

We expand to get:


f(x) = (x - 7)(x^2+ x-6)


f(x) =x^3-6x^2-13x+42

This is a cubic function because the highest degree is 3.
