Answer: correct choice is D

Step-by-step explanation:

You can see that x=4 takes two different values y=7 and y=1. You should remove one of these ordered pairs (4,7) or (4,1).

The answer is (4, 1). To make a table a function, the x values must not repeat. The y values aren’t as important as the x so they can do whatever.
