WebA function f from set A to set B is called an onto function if for each b ∈ B there exists at least one a ∈ A such that f (a) = b. None of the elements are left out in the onto function because they are all mapped to some element of A. Consider the example given below: Let A = {a 1, a 2, a 3 } and B = {b 1, b 2 } then f : A→B.

A minimalist view considers a function as an input-output assignment. Then functions are equal if and only if the same inputs yield the same outputs. In this approach, the domains and ranges of equal functions are identical, while codomains are ignored. tower defense game meaning
