:00.0970, 10.OF UI 12 PUHIS O Points: 0 of 1 Save Test for relative maxima and minima. Use the second-derivative test, if possible. y= -4+8x Select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice. (Type an exact answer. Use a comma to separate answers as needed.) O'A. It is not possible because dry/dx (a) = 0 for all critical points. A sign chart can be used to show that the relative minima/minimum occur(s) at x = and that the relative maxima/maximum occur(s) at x = O B. The second-derivative test shows that the relative maxima/maximum occur(s) at x = because d' y/dx (a) > 0. There are no relative minima. " It is not possible because dy/dx" (a) = 0 for all critical points. A sign chart can be used to show that the relative maxima/maximum occur(s) at x = . There are no relative minima. O P. The second-derivative test shows that the relative minima/minimum occur(s) at x = because day/ dx (a) 0. O E. It is not possible because day/dx" (a) = 0 for all critical points. A sign chart can be used to show that the relative minima/minimum occur(s) at x = .There are no relative maxima. The second-derivative test shows that the relative minima/minimum occur(s) at x = because dry/dx (a)
