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.
In mathematics, a function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output.An example is the function that relates each real number x to its square x 2. function is called injective (or one-to-one, or an injection) if f (a) â  f (b) for any two different elements a and b of the domain. It is called surjective (or onto) if f (X) = Y. That is, it is surjective if for every element y in the codomain there is an x in the domain such that f (x) = y.
