onsider the function (see attached): f(x, y) = (1/3)x3 - (1/3)y3 +3xy +2x - 2y a) Show that point P = (1, −1) is a stationary point of f. b) What is the Hessian matrix H of the function f at the point P? c) Using H, is stationary point P a local maximum, local minimum, saddle point, or none? d) Find all the stationary points of f.
