Question

# The set of ordered pairs (1,19)(2,23) (3,23) (4,29)(5,31) represents the number of tickets sold to a fundraiser. The input values represents the day and the output values represents the number of tickets sold on that day.

a) Make an arrow diagram that represents the relation

b) Is the relation 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: {19 , 23 , 29 , 31}

### We have given the set of ordered pairs (1,19)(2,23) (3,23) (4,29)(5,31) which represents the number of tickets sold to a fundraiser

We have data as

(1,19)(2,23) (3,23) (4,29)(5,31)

Domain (Day) :- {1, 2 , 3 , 4 , 5}

Co- domain(tickets sold) :- {19 , 23 , 29 , 31}

a) Arrow diagram of the given data is

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

The members in the domain set has its square as a output in the co-domain set

Therefore, the given data is a function.

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

The members in the domain set has its square as a output in the co-domain set

Therefore, the given data is a function.

All functions are relations but all relations are not functions.
