Use a graph to estimate the x-values of any critical points

Question

Question: 1. a) Use a graph to estimate the x-values of any critical points and inflection points of f(x) = e^-x2.

b) Use derivatives to find the x-values of any critical points and inflection points exactly

2. If U and V are positive constants, find all critical points of

F(t) = Ue^t + Ve^-t
