Expert Solution
Step 1

The equation is the form z=f(x,y) represents a surface in the space. In this problem the equation of the surface is z=2x2-2y2. In the first part of the problem, we have to give a fixed value to one of the variables and then sketch the corresponding trace. In the second part, we have to identify the surface z=2x2-2y2.
