    Composition function

    Express the function in the form f o g. (Use only elementary functions, but not the identity function, g(x) = x.)

    F(x) = (x^(1/3))/(7+x^(1/3))

    f(x) = ?
    g(x) = ?

    I'm not sure I understand the question. Do they want me create a function for g(x) and f(x) that will make F(x)?

    It would help if you recognise that \displaystyle \frac{x^{\frac{1}{3}}}{7 + x^{\frac{1}{3}}} is a function of \displaystyle x^{\frac{1}{3}}...
