Answer 3

so you have a bunch of coordinates (x,y) with a function no pair of coordinates should have a same y or x value. in order words if you were given a set of coordinates: (3,4) (3,-5) (5,6) (2,7) they would not represent a function because two pairs have the same x value. If two pairs had the same y value but differing x values the same applies.
