Part 1 - For the function f(x) = x3 - x + 1
a) Find the equations of the two tangent lines at the points x = 1 and x = 2, respectively.
b) Find the intersection point of the two tangent lines, if any.
Part 2 - Consider the following demand, supply and total cost functions:
Demand function: p = 50e-0.05q
Supply function: p = 5e0.03q
a) Determine the price and quantity at the equilibrium.
b) Calculate the consumer surplus.
c) Calculate the producer surplus.
Part 3 - If the function f(x, y) = 3x + 2y is subject to the constrain g(x, y) = x2 + y2 = 100.
a) Use Lagrangian multipliers method to find the critical points of the function f(x, y).
b) Plot the function in the 3-D graph in MATLAB.
c) Using Matlab function "fmincon", find the maximum and minimum of the function f(x, y).
Part 4 - Suppose that a restaurant has certain fixed costs per month of $5000. The fixed costs could be interpreted as rent, insurance etc. The marginal cost function of the restaurant is given by:
dc/dq = [0.64(0.17q2 - 32q) + 0.75]
where c is the total cost in dollars of producing q units of good per week.
a) Find the cost of producing q1 = 11750 units, q2 = 17900 units and q3 = 26300 units per week.
b) What do you notice? Explain your results.
