Consider the maximmzation problem maxz s.t. + > = 9zy .y (note, the objective function in simply f(z,y) = z). If by any chance your answer contains roots without rational answers, just leave them as is (e.g. \\'/i), do not compute a numerical approximation. _ o _ review the implicit function theorem! a) (6 points) Find the stationary points, using the Lagrange multiplier method.
