For the polynomial function f(x) = 7 (x²+4)²(x-3)3 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].
