The graph of a function is shown:

D) {-2, 1, 2, 5}

Step-by-step explanation:

The "output" of a function will never be an ordered pair, so we can immediately eliminate options A and B.

In this case, the output refers to the y-values of the function.  

Since the ordered pairs are: (-2, 5), (-1, 1), (2, -2), and (5, 2), we see that the output of this function is: 5, 1, -2, 2.

Thus, choice D is correct.
