問題:
Consider the utiltiy function U = x^2 + 3y which has MUx = 2x and MUy = 3.
The indifference curves for this utility function
(A)will have a diminishing marginal rate of substitution of x for y.
(B)will have a constant marginal rate of substitution of x for y.
(C)will have an increasing marginal rate of substitution of x for y.
(D)will be straight lines.
我的想法:
答案為C 這題不了解意思要問的是什麼 所以不會
謝謝
