The composition symbol is a small circle: (g o f)(x). In mathematics, function composition is an operation that takes two functions f and g, and produces a function h = g f such that h(x) = g(f(x)).In this operation, the function g is applied to the result of applying the function f to x.That is, the functions f : X Y and g : Y Z are composed to yield a function that maps x in domain X to g(f(x)) in codomain Z. You take the function $g(x)$ and put it in place of the $x$ in the function $f$. For $x\in X$ one has $(f\circ g)(x) = f(g(x))$.
