32. If f: A B is an onto function then the range of f is​

Answer 1

Answer:

6

Step-by-step explanation:

Answer 2

A function f : A → B is an onto function, then the range is Co-domain

Given :

A function f : A → B is an onto function

To find :

The range

Solution :

Step 1 of 2 :

Define onto function

We first define co-domain

Co-domain of a function is defined as the set of its possible outputs.

A function f : A → B is said to be an onto function if for every element y in the co-domain B there exists a pre-image x in domain set A such that y = f(x)

Step 2 of 2 :

Find the range

Since f : A → B is onto , then every element in the co-domain B has a pre-image in the domain A

So the range is Co-domain
