Chapter 0.1, Problem 3E

To determine

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

Answer to Problem 3E

The domain of the each given relation is $\left(1,2\right)$ and the range of the each given relation is $\left(5,7,9\right)$ .

No, each given relation is not function.

Explanation of Solution

Given information :

  

The domain of the each given relation is $\left(1,2\right)$ and the range of the each given relation is $\left(5,7,9\right)$ .

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

For example,

For x = 1, there are two values of y , that is y = 5 and y = 9.

Therefore, no, each given relation is not function.
