*[tex \LARGE \ \ \ \ \ \ \ \ \ \ (f\,\circ\,g)(x)]


means the same thing as


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ f\left(g(x)\right)]


Replace the *[tex \LARGE x] in the definition of *[tex \LARGE f(x)] with the definition of *[tex \LARGE g(x)], then simplify. *[tex \LARGE (g\,\circ\,f)(x)] works the same way except that you are going to evaluate g at f(x) instead of the other way around.
