Graph the following function. Then estimate any relative extrema f(x) = x (3- 4X)3 What are the coordinates of the relative extrema? Select the correct choice below and, if necessary, fill in the answer box to complete your choice. (Simplify your answer. Type an ordered pair. Type an integer or decimal rounded to three decimal places as needed. Use a comma to separate answers as needed.) O A. There are three relative extrema. In order of increasing x-value, the coordinates of the relative extrema are and O B. There are two relative extrema. In order of increasing x-value, the coordinates of the relative extrema are and C. There is one relative extremum. The coordinate of the relative extremum is OD. There are no relative extrema
