In mathematics, a surjective function 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 more … Ver mais • For any set X, the identity function idX on X is surjective. • The function f : Z → {0, 1} defined by f(n) = n mod 2 (that is, even integers are mapped to 0 and odd integers to 1) is surjective. Ver mais • Bijection, injection and surjection • Cover (algebra) • Covering map • Enumeration Ver mais A function is bijective if and only if it is both surjective and injective.
