Question

Idk what the right answer is

Answer 1

Answer:

f(x) = x^3 - 2(x)^2+3(x)-1

Step-by-step explanation:

Since h(x) is the combination of function f and g, you have to seprate g(x) from f(x).

To do this, you subsitute x for each and every (8-4x) because g(x)=(8-4x)

h(x) = (8-4x)^3 - 2(8-4x)^2+3(8-4x)-1 so

f(x) = x^3 - 2(x)^2+3(x)-1
