Let F(x) = f(f(x)) and G(x) = F(x)^2.

Also let f(4) = 11, f(11) = 3, f'(11) = 14, f'(4) = 13.

Find F'(4) and G'(4)

Any help guys?

Edit: Thank you so much!
 
If F(x) = f(f(x)) then, by the Chain Rule, F'(x) = f'(f(x)) f'(x).

If G(x) = [F(x)]<sup>2</sup> then, by the Chain Rule, G'(x) = 2[F(x)][F'(x)].

Apply the formulas and plug in the values.
