The following ordered pairs (x, y) define the relation Q. Is Q a function? {(3,-2), (-3, 1). (-2. - 2), (1. - 3)}

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

What am i doing here. add?
