These are all part of the same problem.

Let f(x,y)=6x2y. (25 points) - Sketch the level curves z=c for the following values of c : c=0 c=2 c=4 - Sketch the curve in 3 space given by f(x,y)=6x2y using the information found above. That is, sketch the lovel curves at appropriate height: - What kind of surface is this? Can you find another way to draw this surtace? - What is the domain of this function? - What is the domain of the function f(x,y)=6x2y? Sketch the domain in the xy-plane
