Which set of ordered pairs below is a function?

1.) {(3 , 3), (6 , 1), (2 , 3)}
2.) {(4 , 7), (2 , 8), (4 , 2)}
3.) {(9 , 6), (3 , 1), (7 , 3)}

Please help!! I have been on this problem for awhile now and still can't figure it out.

I dont really feel like graphing it out but i can explain it. so lets say that you had some graph points and when you drew them together it was the shape of a circle so make a line down that circle and the rule is if that circle passes through that line you drew more than 2 times it is not a function, and if it only passes through that line once then it is a function.
