Find the coordinates of the relative extrema for http://img.photobucket.com/albums/v3...leafs/asdf.jpg and determine if the point is a relative maximum or a minimum point. Thanks in advance!

I hope that you know how to find the extrema and minima
(If you don't, tell us)
first derivative is: $5-e^x$
critical point is $ln5$
second derivative is : $-e^x$
value of second derivative at critical point is $-5< 0$
hence it is a maxima(at ln5)
