1. Find ay/3x, and ay/@x2 for each of the following functions: (0) y= 2x -11x x2 + 3x, (c) y = (2x1 + 3) (x2 - 2) (b) y = 7x1 + 6x1x3-9x3 (d) y = (5x1 + 3)/(x2 - 2) 2. Find f, and fy from the following: 2x - 3y (a) f( x, y) = x2 + 5xy- y3 (c) f ( x, y) = * +y X (b) f ( x, y) = (x2 - 3y) (x - 2) (d) f ( x, y) = xy
