Question: (1 point) Suppose f(x, y) = x + y + xy + 4 and D = {(x, y) : |x| 1, |y| 1}. Answer

(1 point) Suppose f(x, y) = x + y + xy + 4 and D = {(x, y) : |x| 1, |y| 1}. Answer the following. 1. Find the absolute maximum of f(x, y) on the region D. Answer: 2. Find the absolute minimum of f(x, y) on the region D. Answer: (1 point) Use Lagrange multipliers to find the minimum value of the function f(x, y) = x + y subject to the constraint xy = 4. Minimum: (1 point) Find the maximum value of f(x, y) = x y8 for x, y 0 on the unit circle. fmax (1 point) A company manufactures x units of one item and y units of another. The total cost in dollars, C, of producing these two items is approximated by the function C=5x+4xy+6y + 900. (a) If the production quota for the total number of items (both types combined) is 77, find the minimum production cost. cost = (b) Estimate the additional production cost or savings if the production quota is raised to 78 or lowered to 76. production cost or savings =
