#### Solutions

Chapter 2.2, Problem 54E
To determine

## To find : The curve is function or not & the domain and range of the function.

Expert Solution

The curve of the graph is not the function of x and here the domain is (33) and the range is (11) .

### Explanation of Solution

Given information : Concept used : A curve in the coordinate plane is the graph of a function if and only if no vertical line intersects the curve more than once.

The domain is the set of X coordinate and the range is the set of Y coordinate of any graph.

Vertical line intersects the curve of graph twice. So, the curve of the graph is not a function of x .

So, here the domain is (33) and the range is (11) .
