Answer:

The answer is: D. (4, 4), (-3, 2), (7, 1), (-7, 2)

Step-by-step explanation:

The others have two instances each where the same input results in a different output. The x is the input and the y is the output. Functions have a unique output for every input.

For A, the (-3, 3) and (-3, 5) make it not a function.

For B, (4, 4), and (4, 3) make it not a function.

For C, (7, 1), and (7, 2) make it not a function.

Hope this helps!! Have and Awesome Day! :-)
