For the function defined below, use a graphing calculator to find a comprehensive graph and then answer parts (a) through (g) below. P(x)=2x+3x3-18x2-7x-60 [-125.1,00) (Type your answer in interval notation. Type integers or decimals rounded to the nearest hundredth as needed.) (e) Determine all intercepts. Determine the y-intercept analytically. Select the correct choice below and fill in any answer boxes in your choice, if necessary. OA. The x-intercept(s) is/are and the y-intercept(s) is/are (Type an integer or decimal rounded to the nearest hundredth as needed. Use a comma to separate answers as needed.) OB. The x-intercept(s) is/are and there are no y-intercepts. (Type an integer or decimal rounded to the nearest hundredth as needed. Use a comma to separate answers as needed.) OC. The y-intercept(s) is/are and there are no x-intercepts. (Type an integer or decimal rounded to the nearest hundredth as needed. Use a comma to separate answers as needed.) OD. There is no x-intercept or y-intercept.
