For the polynomial function below: (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)=-3(X2 + 9)(x-9)3 (a) Find any real zeros of f. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. 0 A. 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.) B. There are no real zeros The multiplicity of the zero is Type a whole number.) (b) The graph of f (c) The maximum number of turning points on the graph is D ▼| the x-axis at the x-intercept (Type a whole number.) (d) Type the power function that the graph of f resembles for large values of Ix.
