QUESTION 2 Suppose the utility function for a consumer of goods X and Y has the simple form U ( X , Y ) = V X . Y a) Graph (sketch) the / =10 indifference curve associated with this utility function b) If X=5, what must Y be equal to on the / =10 indifference curve. What is the marginal rate of substitution (MRS) at this point? c) In general, develop an expression for the MRS for this utility function, showing how this can be interpreted as the ratio of marginal utilities for X and Y
