How do I calculate and do the question?

For each of the following utility functions, find the MRS1,2 = MU2 MU1 at the bundle (11, 4). a) u(x1, x2) = Inx1 + Inx2 b) u(1, x2) = min{x1, 22} c) u(x1, x2) = 4x1 + 922 d) u(x1, x2) = Inx1 + 2x2 e) u(x1, 2) = (4x1 + 9x2)3 f) u(a1, ac2) = a1+ 23Consider the preferences represented by the following indifference curves. These preferences are (check all that apply - if there is not enough information to confirm that one of these applies, leave it unchecked). good 2 good 1 Select one or more: O a. Monotone O b. Strongly monotone c. Convex O d. Strictly convex O e. None of the above
