Consider the following optimization problem: x + 5y min s.t. 4, xy = x 0, y 0. a) [1 point]. Is it a convex optimization problem in the standard form? Justify your argument. If your answer is no, try to convert it into a convex optimization problem. b) [2 points]. Write down the Lagrangian for the optimization problem. Derive the dual optimization problem. c) [2 points]. What is the optimal value of the objective function? What are the KKT conditions? Use the KKT conditions and the optimal solution to solve for the values of the Lagrange multipliers. Wherever needed, ind justify your answer. Go to Settings to a
