Document Summary
The examination counts for 50% towards your (cid:12)nal grade. , (cid:12)nd y x5 (cid:0) 7, then y (e) find y if ey = y3 (cid:0) 2x. 03x + 4p = 30 (a) express the demand x as a function of price p. (b) express the revenue r as a function of the price p. (c) find the elasticity of demand, e(p). A small machine shop manufactures drill bits used in the petroleum industry. The shop manager estimates that the total daily cost (in dollars) of producing x bits is. Find dy for y = x + 3. Evaluate dy for p (a) x = 4 and dx = 0. 1. (b) x = 9 and dx = 0. 12. Compute the following: (a) (b) (c) (d) (e) (f) 3x dx e (4x3 (cid:0) 7x6) dx (x + 9) Find the absolute maximum and absolute minimum value of f (x) = x3 (cid:0) 12x on the interval [(cid:0)3, 3].
