Based on the graph below, how would you describe the curve?

The answer to this question is D

Based on the curve ; The graph is:

        D. The curve is a many-to-one function.

Function--

A function is a relation in which each element is mapped to a single element i.e. no element is mapped to two different elements.

Also, the graph of a function satisfies the vertical line test i.e. any line passing through the domain and parallel to the y-axis should intersect the graph exactly once.

and one-to-one function--

A one-to-one function is such that no two elements have the same image i.e. any line passing through the co-domain and parallel to the x-axis should intersect the graph at most once.

Hence, by looking at the graph we see that the graph is not a straight line.

Hence, it is not a linear function.

            Hence, the correct answer is:

                    Option: D
