Answer parts (a) (e) for the function shown below. f(x) =x° +3x -x-3 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? XF (Type an integer or a decimal. Use a comma to separate answers as needed.) At which x-intercept(s) does the graph cross the x-axis? Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. x= (Type an integer or a decimal. Use a comma to separate answers as needed) O B. There are no x-intercepts at which the graph crosses the x-axis. At which x-intercept(s) does the graph touch the x-axis and turn around? Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. x= (Type an integer or a decimal. Use a comma to separate answers as needed) O B. There are no x-intercepts at which the graph touches the x-axis and turns around. c. Find the y-intercept. The y-intercept is y = (Type an integer or a decimal.)
