A relation is a function if every

*x*has a unique

*y*or every first coordinate(domain) of the ordered pair has exactly one second coordinate(range).

What I don't know is if the repetition of an ordered pair affect the set at all. Will it be considered only as a relation? Or perhaps still a function? Here is an example.

{(6,2) , (4,3) , (5,3) , (6,2) , (7,3) , (2,9)}

Notice the repetition of the ordered pair (6,2). So, will it be considered as a function?
