## badreferences Group Title 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 $$f(x)$$? one year ago one year ago

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.
