what is onto function explain with suitable explanation ​

Answer 1

Answer:

A function f: A-> B is called an onto function if the range of f is B. In other words, if each b EB there exists at least one a E A such that.i f(a)= b, then f is an on-to function. An onto function is also called surjective function.

Examples on onto function Example 1: Let A= {1, 2, 3), B= {4, 5} and let f= {(1, 4), (2, 5), (3, 5)). Show that f is an suriective function from A into B. Solution: Domain = {1, 2, 3} =A Range = {4, 5)

The element from A, 2 and 3 has same range

Sof: A-> B is an onto function.
