Consider three utility functions: Ua(x, y) = x + 10, Ub(x, y) = 2x + 2y, and Uc(x, y) = min {a + 10, 2x + 2y}. a First use the utility function Ua. Draw two indifference curves one for Ua = 12 and one for Ua = 14. Clearly label your diagram to show several points that illustrate the location of the curves. b) Now use the utility function Ub. Draw two indifference curves, again one for Ub = 12 and one for Ub = 14. Again, label your diagram appropriately. c) Now use the utility function Uc. Draw the indifference curve for Ue = 12. Again, label the diagram appropriately
