Homework Help: Math

Posted by Milia on Sunday, June 5, 2011 at 5:35am.

How would you tell if an equation is a funtion or not. I know that it has to have only one y-value for every x...but how do you identify this in an equation (rather than a graph)
ie. y=1/2x-7 (how do i tell if this is a funtion or not)?
Any help would be much appreciated :)
