To Find:The domain of the relation and draw its graph .Is relation is a function.
Answer to Problem 10WE
The domain of the given relation is {-2,-1,0,1,2}.
The relation is function.
Explanation of Solution
Given information:Given relation is
Calculation:
Given relation is
This means that
First case:
Second case:
So, Domain is :{-2,-1,0,1,2}.
So, (-2,-2)(-1,-1),(0.0),(1,-1),(2,-2) are the points of the relation .
Sketch the graph of the given relation by using the points of the relation.
The relation is function there is no vertical line intercept the graph of the relation that is for each x -values, there is one corresponding y- value.
