Let g (x) = 2x and h (x) = x^2+4. Find the value. (gh) (0)

What we do is to substitute to solve.

' (g (h (0)))

g (x) = 2x

g (h (x)) = 2 (x^2 + 4)

(gh) (0) = 2 (0^2 + 4) = 8

If this is supposed to be multiplication, this is the answer.

(g*h) (0)

2x (x^2 + 4) =

2x^3 + 8x =

2 (0) + 8 (0) = 0

If this is supposed to be something else and you forgot the operator between the g and h, let me know and I will redo it for you.
