4. Consider the following function in R" f(Fi, n)=-1) k-1 Find the critical point of this function and show whether it is a local minimum, a local maximum, or neither 5. By examining the Hessian matrix, show that if f(x,y, ) has a local minimum at then g(z, y,) -f(x,y, ) must have a local maximum at that point. Likewise, show that if f has a local maximum, then g must have a local minimum at that point. (ro, yo,...
Problem 2. Determine the critical point(s) of T1 T3 and classify the values of F at the critical points. Show all of your work. As part of your answer, check that the characteristic polynomial of the Hessian at the critical point(s) is equal to (A+ 1)(A2-A-2π, (This factorization will help you to find the eigenvalues of the Hessian.)
