Consider the optimization problem: minimize (x1,x2)RD x3 1 3 4x1 + x3 2 3 16x2 (a) Find the stationary points. (b) Plot the objective function using one of Matplotlib's surface plotters (plot surface or plot wireframe)1. Indicate the local minima, local maxima, and saddle points. (c) Does this problem have a solution? If so, what is it
