Chapter 1.6, Problem 27PPS

To determine

To Express: The relation as set of ordered pairs and write domain and range.

Answer to Problem 27PPS

Ordered pairs $\left(1,2.50\right),\left(2,4.50\right),\left(5,10.50\right),\left(8,16.50\right)$

The domain is $\left\{1,2,5,8\right\}$ and range is $\left\{2.50,4.50,10.50,16.50\right\}$ .

Explanation of Solution

Concept and Formula Used:

Ordered pair is a set of numbers or coordinates written in the form of $\left(x,y\right)$

The set of ‘x’ coordinate is known a domain and the set of ‘y’ coordinate is known as range.

Calculation:

Let the number of fish represent the ‘x’ coordinate and total cost represent the ‘y’ coordinate.

Then the ordered pairs given by

  $\left(1,2.50\right),\left(2,4.50\right),\left(5,10.50\right),\left(8,16.50\right)$

The set of ‘x’ coordinate is known a domain and the set of ‘y’ coordinate is known as range.

The domain is $\left\{1,2,5,8\right\}$ and range is $\left\{2.50,4.50,10.50,16.50\right\}$ .
