Using second derivative test for the critical points of the curve y = x - 3x² – 9x + 20 , which of the following statements is true? At x =-1, y" is negative, concave downward, hence, y (-1) is a relative maximum value. A) At x = 3 , y" is positive, concave upward, hence, y (3) is a relative maximum value. B) At x= -1, y" is negative, concave downward, hence, y (-1) is a relative minimum value. C) At x = 3, y" is positive, concave downward, hence, y (3) is a relative minimum value. D)
