Injective function

Every element of the function's codomain is the image of at most one element of its domain.

Surjective function

f: A -> B is surjective when all elements of B are mapped to by A.
The range is the same as the codomain.

Bijective function

A function which is both surjective and injective.

Inverse of a function

A function ƒ(y) = x, denoted by ƒ⁻¹(x) such that the domain of the function ƒ(x) becomes the range of the inverse function ƒ⁻¹(x), and the range of ƒ(x) becomes the domain of ƒ⁻¹(x) ; the function will only have an inverse function if it is bijective.

Composite function

A combination of two functions such that the output from the first function becomes the input for the second function

A relationship from one set (called the domain) to another set (called the range) that assigns to each element of the domain exactly one element of the range.
