0 k-man 26 Report post Posted June 25, 2014 F'(x) = f'(f(x)) * f'(x) G'(x) = 2 * F(x) * F'(x) So, for x=4 F'(4) = f'(f(4)) * f'(4) = f'(9) * 6 = 15 * 6 = 90 G'(4) = 2 * F(4) * F'(4) = 2 * 2 * 90 = 360 Share this post Link to post Share on other sites

Let F(x) = f(f(x)) and G(x) = (F(x))

^{2}and f(4) =9, f(9)=2, f'(9)=15, and f'(4)=6What is F'(4) and G'(4)?
