That is somewhat of a misrepresentation of L'Hopital's rule. Dividing by zero is still undefined, L'Hopital's rule uses properties of derivatives to find a value for a limit when it seems undefined at first. I still can't divide by zero, but I can tell you what a function is doing when it is approaching dividing by zero. (yeah the difference is small, but one is impossible, the other doesn't have to be) Also, if you instead use a limit that approaches x/0, there is no reason for it to be equal to +infinity, -infinity is just as valid (and much less than 3)
