Question 8 Find the location of the indicated absolute extremum for the function. Maximum O No maximum O X = 4 O x = -1 O X = 1Question 5 Provide an appropriate response. Suppose the derivative of the function y : f(x) is y' : (x - 2) 2(X + 7). At what points, if any, does the graph off have a local minimum or local maximum? (9 no local minimum or local maximum 0 local minimum at x = 2 0 local maximum at x = -7 0 local minimum at x = -7 Question 4 5 points Solve the problem. From a thin piece of cardboard 20 in. by 20 in., square (X in by x in) corners are cut out so that the sides can be folded up to make a box What is the function ofthe volume? 0 V = x(20 - X)( ZO-X) O V = 2x(20 - 2x)( 20-2x) O V = x(20 2x)( 20-2x) O v = 2x(20 - x)( 20-xx)
