# Srinu needs to advertise his company . he Considers several different brochures of different lengths and areas. He presents the data as ordered pairs (4,24) (5,35 )(8,24) (2,20) (9,27).

Represent it in an arrow diagram and explain whether it is a function or not .

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: function.

### We have given the following data of Srinu’s company

(4,24) (5,35 )(8,24) (2,20) (9,27)

Arrow diagram for the given data will be

We have drawn the arrow diagram of the given data

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

Therefore, the given data is a function.

Note: All functions are relations but all relations are not functions.
