Whether the function

Answer to Problem 9E
The function
Explanation of Solution
Use horizontal line test to determine whether the function
Horizontal line test states that the graph of the function is one-to-one function if and only if a horizontal line intersects the graph exactly once.
Sketch the graph of the function
From Figure 1, it is observed that the horizontal line intersects the curve exactly at once which means it passes the horizontal line test. Therefore, the function
