I am assuming you are familiar with coordinates representing x and y coordinates so (x,y). If this is unfamiliar let me know.
For a function, there cannot be a repeat of xs unless every one goes to the same y. So for instance if (3,4)(3,5) were in the list this would not be a function because 3 is used twice but goes to a different number each time.
