(5 points) Suppose that you have two consumption choices: good X, and good Y. An indifference curve is the set of consumption s choices with a CONSTANT utility. For example if X = 10 and Y - 6 gives the same utility as consuming X = 11 and Y = 5, than these are both points on the same indifference curve. An indifference map is the set of all indifference curves for EVERY given utility. The Cobb-Douglas utility function gives a simple indifference map U = Xay1-a, where 0
