WebSurjective Function. Bijective Function. 1. A function will be injective if the distinct element of domain maps the distinct elements of its codomain. A function will be surjective if one more than one element of A maps the same element of B. Bijective function contains both injective and surjective functions. 2. WebAlternatively, f is bijective if it is a one-to-one correspondence between those sets, in other words both injective and surjective. Example: The function f(x) = x2 from the set of positive real numbers to positive real numbers is both injective and surjective. Thus it is also bijective .

WebA bijection between two infinite sets A and B is a function f that maps each element of A to a unique element of B, and vice versa, such that no elements are left unmapped. In other words, f is both injective (one-to-one) and surjective (onto).
