Homework Help: Composite Functions

  1. Mar 22, 2008 #1
    Let f(x)=g(h(x))

    where h(2)=3
    h'(2)=4
    g(3)=5
    g'(3)=5

    find f'(2)

    Attempt at a solution

    I tried to used the product rule, but I don't think composite function are the same as multiplying. Does anyone have any suggestions!?!?

    The product ruile? Why in the world would you use the product rule when there is no product here? How about the chain rule?
