Math Problem Statement
yequalsRootIndex 3 StartRoot 2 x cubed plus 16 EndRoot entify where the curve is increasing or decreasing. Select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice. A. The curve increases on the open interval(s) left parenthesis negative 2 comma 0 right parenthesis comma left parenthesis 0 comma infinity right parenthesis and decreases on the open interval(s) left parenthesis negative infinity comma negative 2 right parenthesis. (Type your answers in interval notation. Use a comma to separate answers as needed.) B. The curve increases on the open interval(s) left parenthesis negative infinity comma negative 2 right parenthesis comma left parenthesis negative 2 comma 0 right parenthesis comma left parenthesis 0 comma infinity right parenthesis and does not decrease. (Type your answer in interval notation. Use a comma to separate answers as needed.) C. The curve does not increase and decreases on the open interval(s) enter your response here. (Type your answer in interval notation. Use a comma to separate answers as needed.) D. The curve neither increases nor decreases. Suppose f is continuous on [a,b] and differentiable on (a,b). If f prime(x)greater than0 at each point xis an element of(a,b), then f is increasing on [a,b]. Similarly, If f prime(x)less than0 at each point xis an element of(a,b), then f is decreasing on [a,b].
