Function composition in mathematics is an operation that combines two functions, f and g, to produce a new function h = g ∘ f, where h(x) = g(f(x)). This means the function g is applied to the result of applying the function f to x, creating a chain where the output of one function feeds into the input of another. The properties of function composition are similar to those of composition of relations, but it differs from multiplication of functions, notably in that it is not commutative.
