I have a very messy question.\[f\left(f\left(f(x)\right)\right)=g(x)\]Is there a resource you can direct me to that discusses the general case of solving for \(f(x)\)?

    I misstated my question by being too vague, but I found the solution nonetheless. http://en.wikipedia.org/wiki/Chebyshev_polynomials

    I was looking for general case studies so I could pick out Chebyshev polynomials.
