In each of the following plots, determine whether the specified points are feasible, infeasible, local optimal, and/or global optimal in the depicted mathematical program over two continuous variables. Dashed lines indicate contours of the objective function, and solid lines show constraints.

(a) Maximize problem; x112 = 15, 02, x122 =

12, -12, x132 = 13, 32, x142 = 11, 32

(b) Minimize problem: x112 = 11, 32, x122 = 13, 32, x132 = 13, 22, x142 = 13, 02
