Need with the composition of functions. i have attached a screenshot of the question.

h(h(x)) = + 6x² + 12

f(f(x)) = x

note that h ○ h = h(h(x))

To evaluate substitute h(x) into h(x)

h(h(x)) = h(x² + 3 ) = (x² + 3 )² + 3 = + 6x² + 9 + 3 = + 6x² + 12

Similarly for f ○ f

f(f(x)) = f()

        = 9 / (2 × = 9 / = = x

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x

step-by-step explanation:

a child is 12 years old, and his father is 32 years older. in how many years will the age of the father be 2 times the age of the child?

******************

this needs to be the answer format, or else your answer is incomplete.

if the number of years is x, then the equation is

in __ years
