Concept explainers
In Problems 13-24, determine whether the graph is that of a function by using the vertical-line test. If it is, use the graph to find:
(a) The domain and range
(b) The intercepts, if any
(c) Any symmetry with respect to the , the , or the origin

To find: The given graph is that of a function by using vertical-line test; if it is, using the graph to find.
- The domain and range;
- The intercepts, if any;
- Any symmetry with respect to the , the or the origin.
Answer to Problem 11AYU
Not a function.
Explanation of Solution
Given:
The following graph
Calculation:
The given graph is not a graph of a function because there is a vertical line that interests the graph at more than one point. For example the input 2 corresponds to two outputs 2 and . This is why the graph does not represent a function.
