Express the given function h as a composition of two functions f and g so that h(x)=(fog)(x) where one of the functions is 8x-9.
h(x)=(8x-9)^2

Let f(x) = 3 − x . find the average rate of change of f(x) from x = a to x = a + h and simplify your answer so that no single factor of h is left in the denominator.
