Question

Express each relation as a set of ordered pairs. Describe the domain and range.

Short answer

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 $\left\{2.50,4.50,10.50,16.50\right\}$.

Step-by-step solution

Step 1. 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 as a domain and the set of ‘y’ coordinates is known as range.

Step 2. Calculation.

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

Then the ordered pairs are given by

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

Step 3. Conclusion.

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

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