2. Consider the function f:R? R defined by f(z,y) = +y* 3e\"y. (a) Show that f has exactly one critical point. (b) Show that the critical point is a local minimizer but not a global minimizer of f. (This shows that the property found in the foregoing problem is in fact a property that is unique to the one-dimensional setting.)
