  1. Feb 17, 2015 #1
    1. The problem statement, all variables and given/known data

    find F(7) and F(a^2-2) (a≥2). Simplify.

    3. The attempt at a solution
    Not sure maybe F(7^2-2) therefore F(47)? Not sure what this question is asking me to do.

    Please help

    You're going to have to tell us more. What is F?

    Yes. Unless we know something more about F, there is no way to simplify the two expressions.
