Also, y(0) = -1, thus the 1 equation required is y - (-1) = 2(x - 0) or y = 2x - 1. 2.4.28 g(x) = 1+ 1 3x = 1+ 1 1/2 3x g (x) = 1 2 1+ 1 3x -1/2 1+ -1/2 1 3x 1 = 2 = - 1 1+ 3x 1 6x2 1+ - 1 3x2 1 3x 2.5.12 (a) R (q) = 240 - 0.1q , so, at a production level of 80 units per month, the marginal revenue is R (80) = 232 (b) R(81) - R(80)=$231.95 End. ...
