Question

If range of is a proper subset of the co-domain of , then the function is called _____ function.​

Answer 1

Step-by-step explanation:

The Codomain is the set of values that could possibly come out. The Codomain is actually part of the definition of the function. And The Range is the set of values that actually do come out. Example: we can define a function f(x)=2x with a domain and codomain of integers (because we say so).

Answer 2

Answer:

The codomain is the set of all possible values which can come out as a result but the range is the set of values which actually comes out.

So if function has range and codomain equal then that function is called onto function.

A function f:A→B is onto if, for every element b∈B, there exists at least an element a∈A such that f(a)=b.

I hope that you have got your answer and understood it☺️☺️☺️
