Help Please.

Someone said it was C.

OpenStudy (alex6799):

what do you think it is?

OpenStudy (anonymous):

C is correct, because for any x there has to be only one y.

OpenStudy (darthvader2900):

@alex6799 I think it is C

OpenStudy (anonymous):

In A, B and D you can see that the same x could have two different ys which would not be a function.

OpenStudy (darthvader2900):

Okay, thanks @AlexLin

OpenStudy (alex6799):

it is C

OpenStudy (darthvader2900):

Thanks you both.
