1. f (x, y, z) = 1 + 2xy3+ 3y −xy z Find the following: a) fx(x, y, z) b) fx(1, 1, 1) c) fz(x, y, z) d) fz(1, 1, 1)
2. If your weekly cost, C, (in dollars) to manufacture L laptops and D desktops is: C(L, D) = 5000 + 50L + 40D −LD What is the marginal cost of a laptop at a production level of 80 laptops and 30 desktops?
