Take it step-by-step.

Take pen and paper. Plot a cartesian coordinate system with x1 and x2 at the axes.

For 1.6 you have 2 linear constraints. Plot the lines of their boundary, sketch in the regions

where they are satisfied. That gives you the allowed region for your optimization. Calculate

the gradient of your function F, plot that arrow (since it is a linear function in x1 and x2). Plot that

arrow on the graph.

For 1.7 do the same. Step by-step. Here there will be another couple of steps since you have

additional constraints.

For doing this with matlab: have a look at pcolor, double and meshgrid.
