WebIn mathematics, a surjective function (also known as surjection, or onto function / ˈ ɒ n. t uː /) is a function f such that every element y can be mapped from element x so that f(x) = y.In other words, every element of the function's codomain is the image of at least one element of its domain. It is not required that x be unique; the function f may map one or …
