You can put this solution on YOUR website! Does the set of points {(1,2),(3,2),(6,10),(-3,5)} describe a function? How do you know?
------
Yes: All the x-values are different so there
is no question. It is a function.
----
If a couple of the x's were the same you would check
to see if the y-values were different for those
equal x's. If they were, you would not have a function.
