Is the following relation a function?
x y
-1 -2
2 3
3 1
6 -2
answer

no

yes

Yes, it is definitely a function. Although one might say that it is not a one to one or injective function because of the presence of (-1,-2) and (6,-2).. The correct option among the two options that are given in the question is the second option. I hope that this is the answer that has actually come to your desired help.
