WebFeb 21, 2024 · Bijective function is a function f: A→B if it is both injective and surjective. A function is surjective or onto if for every member b of the codomain B, there exists at least one member of domain A such that f(a) = b. A function is injective or one-to-one if for every member b of the codomain B, there is at most one a that is a member of ... WebExamples on Surjective Function. Example 1: Given that the set A = {1, 2, 3}, set B = {4, 5} and let the function f = { (1, 4), (2, 5), (3, 5)}. Show that the function f is a surjective function from A to B. We can see that the element from set A,1 has an image 4, and both 2 and 3 have the same image 5. Thus, the range of the function is {4, 5 ... free avi to jpg converter
