  1. Sep 5, 2006 #1
    just started my precalculus class and i can not understand whats going on and its makes me mad too. In our book we are on 1-2 Composition and Inverses of Functions like for this one problem:

    Find [f of g] (x) and [g of f] (x).
    1. f(x)= 1/2x-7
    g(x)= x=6



    and this problem

    f(x)=3x^2 and g(x)=x-4 please help

    And why would you put a thread title "Precalculus" in the "Calculus & Beyond" section instead of in the section called "Precalculus Mathematics"?
