we conclude that the function is one-to-one.
Step-by-step explanation:
A function will a one-to-one function if it
In other words,
The function will be one-to-one if it passes the vertical line test, and also if the horizontal line only cuts the graph of the function in one place.
The reason is that there must be only one x-value for each y-value.
Given the function
Have a look at the attached graph.
Therefore, we conclude that the function is one-to-one.
