Answer 2

HELLO DEAR,

GIVEN:- What is not true about relations and functions?

A) Every function is a relation

B) Every bijection is a relation

C) Every relation is a function

D) Every surjection is a relation

SOLUTION:-

C) Every relation is a function.

We know that , ' Every function is a relation but every relation is not a function.'

So, A) Every function is a relation, yes it is true.

B) Every bijection is a relation

Bijection is also a function , if a function is one-one and onto then it is called bijective function.

So, it is also true.

C) Every relation is a function.

It is not true .

D) Every surjection is a relation.

Surjection is also a function , if a function is onto then that function is called surjection.

So, it is true.

THANKS.
