Given information
Graph of the function is given and one needs to check that whether the given function is one-to-one or not.
Step-by-step explanation
Step 1.
A function will be one-to-one if a horizontal line never crosses the function's graph more than once. If one draws the horizontal line on the graph it can be seen that the line crosses the graph at two places where the function takes the value , which is shown in the figure. Thus, the given function is not one-to-one.
