In mathematics, is is important to read the directions before attempting to work any problems. You are NOT expected to able to work any problems. You are NOT expected to be able to work Problems 11-60 at this time. You ARE expected to be able to work those problems AFTER reading this text. So for now, just place each assigned question in one of the following categories:
Yes. I know how to start this problem.
No. I don’t think I know how to start this problem.
Hopeful. If someone shows me how to proceed, I think I could answer this question.
Hopeless. I don’t think I’ll ever be able to answer this question.

- (i) For a given constant a > 0, let an investor's preference be represented by the Gaussian utility function U(w)=1-e-aw² For what range of wealth level w will the investor be non-satiated and risk-averse? Explain your answer. (ii) Give an example of a utility function that exhibits DARA and verify it. (iii) Determine the class of utility functions with relative risk aversion coefficient R(w)= w², w> 0.arrow_forward3. Compute the profit corresponding to 12,000 units. 5. A rectangular box is to have a square base and a volume of 20 ft3. The material for the base costs $0.30 per ft2, the material for the sides cost $0.10 per ft2, and the material for the top costs $0.20 per ft2. Letting a denote the length of one side of the base, find a function in the variable x giving the cost of constructing the box. 6. Given the following graph f(x).arrow_forward8. On what intervals, each function continuous? (a) f(x) = 3x11 + 4x²+1 3x²+5x-1 (b) g(x) = x²-4 X, x < 1, QTs the function f(x) continuous at = 1?
