{1} Find the equations and sketch the graphs of at least 5 different level curves for the surfaoe 2:: fling} = my Include in your sketch the level waves 2: = 2, z = -1, 2: = (1,2: =1,a.acl 2: = 2. Sketch these on the same graph so that your illustration looks like a topographic map. Hint: The level curve z = 1 lives in lQuatlracats I and III and the level curve 2 = -1 livw in Quadrants II and IV
