The function A(x) = 0.002x3 - 0.03x2 + 0.14x + 0.05. appromimates the blood alchol concentration in a person's bloodstream X hours after drinking a shot of whiskey. The function only applies to the interval for the first 6 hours. Using a sign chart on the first derivative answer the following questions: A) On what time interval(s), if any, is the blood concentration increasing? B) On what time interval(s), if any, is the blood concentration decreasing?
