Chapter 0.1, Problem 6E

To determine

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

Answer to Problem 6E

The domain of the each given relation is $\left(-8,-7,-4\right)$ and the range of the each given relation is $\left(2,3,5,6\right)$ .

No, each given relation is not a function.

Explanation of Solution

Given information:

  

The domain of the each given relation is $\left(-8,-7,-4\right)$ and the range of the each given relation is $\left(2,3,5,6\right)$ .

It can be seen that each given input does not unique output.

For example,

For x = −4, y has two output values, that is, y = 2 and x = 3.

Therefore, no, each given relation is not a function.
