Chapter 1.2, Problem 35E

To determine

To state: relation in table as a set of ordered pair, and also state the domain and range.

Answer to Problem 35E

Set of ordered pairs = $\left\{(-1,8),(0,4),(2,-6),(5,-9)\right\}$

Domain = $\left\{-1,0,2,5\right\}$

Range = $\left\{-9,-6,4,8\right\}$

Explanation of Solution

Given information: The values of x and y is shown below.

x	-1	0	2	5
y	8	4	-6	-9

Calculation:

From the table, the set of ordered pairs of the relation in (x, y) is as follows:

  $(-1,8),(0,4),(2,-6),(5,-9)$

Since all the possible values of x is a domain. So, the domain value is $\left\{-1,0,2,5\right\}$ .

All the possible values of y represent the range. So, the range is as follows:

  $\left\{-9,-6,4,8\right\}$
