Question

# Is the relation shown below a function ? Explain.

Hint:

### An ordered pair is represented as (INPUT, OUTPUT)

A function from set A to the set B is a relation which associates every element of a set A to unique element of set B.

## The correct answer is: { 4, 6 , 2 , 8 , 5 }

### We have given the data in the tabular format

We will convert it into point format

As (3,4) , (4, 6) , (1, 2) , (5, 8) , (2, 5)

Domain:- { 3, 4, 1 , 5 , 2 }

Co- Domain:- { 4, 6 , 2 , 8 , 5 }

From the given data we can analyse that each element in the domain input set has exactly one output.

Therefore, the given data is a function.

All functions are relations but all relations are not functions.
