Given: Q(x) = 4x^2 + 20x + 25 / e^x

a) Find the stationary point(s) of Q(x) and give the functional value of the point(s).

b) For each stationery point, indicate whether it is a local minimum or local

maximum and explain why.

I know how to do this problem and find the points, but i don't know how to deal with e^x
