Reconsider the linearly constrained convex programming model given in Prob. 13.4-7. Use the KKT conditions to determine whether (x1, x2) = (2, 2) can be optimal. Consider the following quadratic programming problem: Maximize f (x) = 2x1 + 3x2 – x12 – x22, subject to x1 + x2 ≤ 2 and x1 ≥ 0, x2 ≥ 0. For each of the following functions, show whether it is convex, concave, or neither. (a) f (x) = 10x – x2 (b) f (x) = x4 + 6x2 + 12x (c) f (x) = 2x3 – 3x2 (d) f (x) = x4 + x2 (e) f (x) = x3 + x4 Reconsider the linearly constrained convex programming model given in Prob. 13.6-5.
