Which of the following sets of ordered pairs is a function? {{-5,-4),(-5,-2),(-5,0)}
{(0,3),(0,2),(0,3)}
{(1,0),(2,0),(3,0)}
{(-3,1),(-2,0),(-3,-2)

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.

The answer simplified would be. -6300x
