Chapter 1.4, Problem 9CYU

To determine

  $\left\{3,1,4\right\}$

To calculate:To represent each relation in a table and determine the domain and range

Answer to Problem 9CYU

Relation in table is given as follows

x	y
3	4
1	5
4	2

Domain is and range is $\left\{4,5,2\right\}$

Explanation of Solution

Given information:Set of ordered pairs is $\left\{\left(3,4\right),\left(1,5\right),\left(4,2\right)\right\}$

Formula Used:

In an ordered pair $\left(x,y\right)$

Domain is the set of all first elements of ordered pairs (x-coordinate)

Range is the set of all second elements of ordered pairs (y-coordinate)

Calculation:

Set of ordered pairs is given as

  $\left\{\left(3,4\right),\left(1,5\right),\left(4,2\right)\right\}$

Now, above relation is tabular format is

x	y
3	4
1	5
4	2

Domain and range are as follows:

  $D=\left\{3,1,4\right\}$

  $R=\left\{4,5,2\right\}$
