Chapter 8.8, Problem 11E

To determine

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

Answer to Problem 11E

The domain of the given graph is $\left\{-3,-2,-1,0,1,2,3\right\}$ , the range is $\left\{-2,-1,0,1\right\}$ , and the given relation isa function.

Explanation of Solution

Given information:

The given graph is,

  

The domain of the given graphis $\left\{-3,-2,-1,0,1,2,3\right\}$ and the range is $\left\{-2,-1,0,1\right\}$ .

A relation is said to be a function if x -co-ordinate is paired with exactly one y -co-ordinate. In this relation x -co-ordinate is paired with exactlyone y -co-ordinate, so the given relation is a function.

Hence, the given relation isa function.
