What's part D

For the polynomial function f(x) = (2x2 + 5) (x2 +9) , answer the following questions. (a) List each real zero and its multiplicity. (b) Determine whether the graph crosses or touches the x-axis at each x-intercept. (c) Determine the maximum number of turning points on the graph. (d) Determine the end behavior; that is, find the power function that the graph of f resembles for large values of (b) Select, the correct choice below and, if necessary, fill in the answer box(es) to complete your choice. O A. . The graph crosses the x-axis at (Type an integer or a simplified fraction. Use a comma to separate answers as needed.) O B. The graph touches the x-axis at (Type an integer or a simplified fraction. Use a comma to separate answers as needed.) O C. The graph touches the x-axis at and crosses at (Type integers or simplified fractions. Use a comma to separate answers as needed.) D. The graph neither crosses nor touches the x-axis. (c) The maximum number of turning points on the graph is 5. (d) The power function that the graph of f resembles for large values of |x| is y = 5x6
