You can put this solution on YOUR website! identify if this is a function or not and to state if it is discrete or continuous...i have no idea wat iam doing... this is the problem ((7,8)(7,5)(7,2)(7,-1))
--------------
It is not a function because 7 is paired with more than one
number, as you can see.
It is a discrete Relation: discrete because there are points
between which there are no other points.
