Chapter 0.1, Problem 1E

To determine

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

Answer to Problem 1E

The domain of the each given relation $\left(2,3,1\right)$ and the range of the each given relation $\left(7,10,6\right)$ .

Yes, each given relation is function.

Explanation of Solution

Given information :

  $\left\{\left(2,7\right),\left(3,10\right),\left(1,6\right)\right\}$

The domain of the each given relation $\left(2,3,1\right)$ and the range of the each given relation $\left(7,10,6\right)$

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

For example,

For x = 2, y = 7.

For x =3, y = 10.

For x =1, y = 6.

Therefore, yes, each given relation is function.
