Question

What is the domain and range?

{(4,2), (-9,2), (5,4), (4,17)}

Answer 1

Hey there!!

What is a coordinate form?

... Coordinate form is written as ( x , y )

What is domain?

... Domain are also called as the 'x' values.

What is the range?

... Range is the other word for the 'y' values.

Given ordered pairs :-

( 4 , 2 ) ; ( -9 , 2 ) ; ( 5 , 4 ) ; ( 4 , 17 )

Hence, the domain is :-

... { 4 , -9 , 5 )

Hence, the range is :-

... { 2 , 4 , 17 )

Remember :- The values "can not" be repeated!

Hope my answer helps!!

Answer 2

Domain = {4,-9,5}

Range = {2,4,17}

Explanation:

We are given ordered pairs as

{(4,2), (-9,2), (5,4), (4,17)}

This is a subset of cartesian product AXB where

A = {4,-9,5} and B = {2,4,17}

Note: Repeated values are written only once in the set.

Hence we find that 4 is mapped on to 2 and 17,

-9 to 2 and 5 to 4

Domain = I item in the ordered pair of mapping = {4,-9,5}

Range = II item in the ordered pair of mapping = {2,4,17}
