What does the phrase "such that" mean in this sentence?
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. If (as is often done) a function is identified with its Ver mais Given fixed A and B, one can form the set of surjections A ↠ B.

Ver mais WebInto function is a type of function where at least one element of the co-domain will not have a pre-image in the domain. Suppose there are two sets, A (domain) and B (codomain). If at least one element of set B is not associated with an element in set A then such a function will be known as an into function. The range of an into function will ...
