Function composition. In mathematics, function composition is the pointwise application of one function to the result of another to produce a third function. For instance, the functions f : X â Y and g : Y â Z can be composed to yield a function which maps x in X to g(f(x)) in Z.
Intuitively, composing two functions is a chaining process in which the output of the first function becomes the input of the second function. The composition of functions is a special case of the composition of relations, so all properties of the latter are true of composition of functions. The composition of function has some additional properties.
