1. If U = f (x, y) is the utility function for goods X and Y, the marginal utility of X is U x and the marginal utility of Y is ∂U/∂y. If U = x2y2, find the marginal utility of
(a) X.
(b) Y.
2. Utility If the utility function for goods X and Y is U = xy + y2, find the marginal utility of
(a) X.
(b) Y.
