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 ... WebEvery onto function has a right inverse and every function with a right inverse is an onto function. When we compose onto functions, the result will be onto function only. Example: Let A= {1,5,8,9) and B {2,4} And f= { (1,2), (5,4), (8,2), (9,4)}. Then prove f is a onto function. Solution: From the question itself we get, A= {1,5,8,9) B {2,4}

WebKnow how to write a proof to show a function is one-to-one. To show that a function f is not one-to-one, all we need is to find two different x -values that produce the same image; that is, find x1 ≠ x2 such that f(x1) = f(x2).
