Onto function diagram

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.

Also, the definition of a function does not require that the range of the function must equal the codomain. The range is always a subset of the codomain, but these two sets are not required to be equal.

WebThe Codomain is actually part of the definition of the function. And The Range is the set of values that actually do come out. Example: we can define a function f (x)=2x with a domain and codomain of integers (because we say so). But by thinking about it we can see that the range (actual output values) is just the even integers. WebOnto Function is also called surjective function.

Example: Define f : R R by the rule f(x) = 5x - 2 for all x R.Prove that f is onto.. Proof: Let y R. (We need to show that x in R such that f(x) = y.). If such a real number x exists, then 5x -2 = y and x = (y + 2)/5. x is a real number since sums and quotients (except for division by 0) of real numbers are real numbers.
