5.8 Suppose the utility function for goods Xand Fis given by utility = U(X, Y) = XY+ Y.

a. Calculate the uncompensated (Marshallian) demand functions for Xand Fand describe how the demand curves for X and F are shifted by changes in / or in the price of the other good.

b. Calculate the expenditure function for X and F

c. Use the expenditure function calculated in part

(b) to compute the compensated de mand functions for goods X and F Describe how the compensated demand curves for Xand Fare shifted by changes in income or by changes in the prices of the other good.
