For the polynomial function f(x) =7(x -4)(x + 6) 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 x. (a) Find any real zeros of f. Select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice. O A. The real zero of f is with multiplicity (Type an exact answer, using radicals as needed. Type integers or fractions.) O B. The smallest zero of f is with multiplicity The largest zero of f is with multiplicity (Type an exact answer, using radicals as needed. Type integers or fractions.) O C. The smallest zero of f is with multiplicity The middle zero of f is with multiplicity The largest zero of f is with multiplicity (Type an exact answer, using radicals as needed. Type integers or fractions.) O D. There are no real zeros
