For the polynomial function below, answer parts (a) through (d). (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 x. f(x)=8(x+9) (x+8) 2 (a) Find any real zeros of f. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. The real zero(s) of f is/are (Type an exact answer, using radicals as needed. Use integers or fractions for any numbers in the expression. Use a comma to separate answers as needed.) OB. There are no real zeros.
