    Does this mean rewrite  f(x) as:

    f(x)=g(h(x))

    where  g and  h are in some sense simpler?

    You're question is kind of vague. Are you looking for something like this?

    f(x)=g(h(x))

    '

    How about h(x)=x^3, then g(x)=(2x-7)^5 or maybe something simpler yet?

    Shouldn't it be:

    f(x)=g(h(x))

    Where

    g(x)=x^{5} and h(x)=(2x^{3}-7)

    There is no unique solution.
