Does this relation define a function? Just tell me if I did it wrong or correct, thanks.?

Q: Does the relation [ (1,2), (3,3), (1,5), (2,0) ] define a function? Explain.

I think it doesn't define a function because two 1's repeat.

Am I correct?

    You are correct. It's only a function if for every x there is only one y.
