Concept explainers
To check: Whether the graph of given function is one-to-one or not.
Answer to Problem 1E
The graph of the given function is not one-to-one.
Explanation of Solution
Given information: The graph of the function
Horizontal line test: The graph of a function is said to be one-to-one if a horizontal line intersects the graph only at one point.
Draw a horizontal line on the graph of the function.
From the graph, it can be seen that horizontal line will intersect the graph at two points.
Therefore, the graph of the given function is not one-to-one.
