- (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.
