Answer questions 2 and 5

2. Differentiate the function f (x) -47 + 23 3x2 - r dy 3. If y = vu and u = 23 - r, use the chain rule to determine dx 4. Find the absolute extrema of the function f (x) = x3 - 6x2 + 11 on the interval [1, 5]. 5. If the price charged for a unit of a certain commodity is p dollars, then I units will be sold in a certain city, where p = 151 - 0.0001x. Determine the number of units produced and sold that maximize the revenue from this commodity
