4. UTILITY (10 POINTS) You consume only 2 goods: x and x2. Your utility function for consuming these goods is u (1, X2) = (x1 + 3) (x2+1) (a) (2 POINTS) What is your utility level when 1 = 2 and x2 = 2? (b) (2 POINTS) What is your marginal utility for x1 when x1 = 2 and 12 = 2? (c) (2 POINTS) What is your marginal utility for x2 when x1 = 2 and 2 = 2? (d) (4 POINTS) Derive an expression for the indifference curve through the consumption bundle where x1 = 2 and x2 = 2. Write the equation to express x2 as a function of x1. 5. UTILITY (10 POINTS) You consume only 2 goods: x, and 2. Your utility function for consuming these goods is u (x1, X2) = In (21) + 23 (a) (2 POINTS) What is your utility level when a1 = 1 and x2 = 4? (b) (4 POINTS) Derive an expression for the indifference curve through the consumption bundle where m1 = 1 and 72 = 4. Write the equation to express x2 as a function of 1. (c) (4 POINTS) Calculate your marginal rate of substitution at $1 = 1 and 2 = 4. Activate
