1) Evaluate the second order conditions for problems (a) and (b) below. a) U x 1 2 x 1 2 subject to 50 5x1 10x 2 1 2 b) U (x 3)(y 5) subject to 30 3x 2y 2. Given the constraint, find the stationary points for the following function and evaluate the second order conditions. Use the Lagrange technique. Z e (3x 2 0 x - y - 6x 2y2 - y)
