Answer parts (a)-(e) for the function shown below. \( \mathrm{f}(\mathrm{x})=\mathrm{x}^{3}+3 \mathrm{x}^{2}-\mathrm{x}-3 \) a. Use the leading coefficient test to determine the graph's end behavior. Which statement describes the behavior at the ends of \( \mathrm{f}(\mathrm{x})=\mathrm{x}^{3}+3 \mathrm{x}^{2}-\mathrm{x}-3 \) ? A . The graph falls to the left and rises to the right. B . The graph rises to the left and falls to the right. C. The graph falls to the left and to the right. D . The graph rises to the left and to the right. b. Find the x -intercepts. State whether the graph crosses the x -axis, or touches the x -axis and turns around, at each intercept. What are the x -intercepts? \( \mathrm{x}=\square \) (Type an integer or a decimal. Use a comma to separate answers as needed.) )
