We just learned this (well, a much more basic version) today in calculus, and I have no idea where to start on this problem.

"your task is to first find two outer functions that "squeeze" the given one to the right of zero; then compute the appropriate limits and make your conclusion"

i searched and found the above thread (which made me laugh because it's the same problem!), but im still very lost

thanks
