To check: Whether the graph of given function is one-to-one or not.

Answer to Problem 2E
The graph of the given function is one-to-one.
Explanation of Solution
Given information: The graph of the given is shown below:
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 every horizontal line will intersect the line only at one point.
Therefore, the graph of the given function is one-to-one.
