Homework Help: Functions

Posted by Soly on Saturday, September 1, 2007 at 2:50pm.

I need help with the following question. I am sure how to tell if something is a function or not.

Determine whether the realtion is a function.

{(-6,2),(-2,5), (3,2),(3,-7)}

I think its not a function, but then again I think it is cause you have different x's going to different y's.

No one has answered this question yet.
