Chapter 0, Problem 1PR

To determine

the domain and range of each given relation and whether each relation is a function.

Answer to Problem 1PR

The domain of the each given relation $\left(-3,8,14\right)$ and the range of the each given relation $\left(1,4,6\right)$

yes, each given relation is a function.

Explanation of Solution

Given information :

  $\left\{\left(14,1\right),\left(-3,6\right),\left(8,4\right)\right\}$

The domain of the each given relation $\left(-3,8,14\right)$ and the range of the each given relation $\left(1,4,6\right)$

It can be seen that each given input has the unique output.

For example,

For x = −3, y = 1.

For x = 8, y = 4.

For x = 14, y = 6.

Therefore, yes, each given relation is a function.
