Chapter 8.8, Problem 1E

To determine

To find: Thedomain and the range of the relation and whether the given relation is a function or not.

Answer to Problem 1E

The domain of the given relation is $\left\{2,3\right\}$ , the range of the given relation is $\left\{0,3,4,6\right\}$ , and the given relation is not a function.

Explanation of Solution

Given information:

The given relation is,

  $\left\{\left(3,4\right),\left(2,3\right),\left(3,6\right),\left(2,0\right)\right\}$

The domain of the given relation is $\left\{2,3\right\}$ and the range of the given relation is $\left\{0,3,4,6\right\}$ .

A relation is said to be a function if x -co-ordinate is paired with exactly one y -co-ordinate. In this relationx -co-ordinate is paired with more than oney -co-ordinate, so the given relation is not a function.

Hence, the given relation is not a function.
