I simplified and set it equal to zero. the critical numbers i got were 0 and e^1/2 however the question says I'm wrong

Re: Finding critical numbers

To find critical points, you find the derivative. Then you set the derivative equal to zero. You then solve for x. Those are then *candidates* for local maxima or minima.
