QUESTION S Graph the following function on your calculator: f(x) = -0.0015x4 + 0.54x3 _ 12.6x2 - 5,280x + 288,000 Which of the following statements about f(x) is true? O This function has an absolute maximum of ~ 444,968.58. O This function has four turning points. O A good window to view ALL the turning points and intercepts of this graph is XMIN: -200, XMAX: 200, XSCL: 20, YMIN: -500,000, YMAX: 500,000, and YSCL: 50,000. O The graph is empty, so this function cannot be graphed. O This function has three x-intercepts
