Problem 2: given the function f(x, y)=2xy-e^3x, a) sketch the graph of the level curves generated by c=0, c=4, c=3, c s| 2 and c= 4. b) taking advantage of the level curves from part (a) sketch the graph of the function. c) sketch the graph of the bounded region enclosed by the curves y 40x+10 and y 2x determine the volume of the solid whose base is the region r from part (e) while the top of the solid is bounded by the function f(x, y)-2xy-e d) problem 3: use your calculator to approximate the area of the region bounded by the graph of of the polar equation rsi sketch the graph of the region
