Answer the question.Let f be a polynomial function with a leading coefficient of 1 and having the following zeros: 5 (multiplicity 1), -3 (multiplicity 3), 9 (multiplicity 2), and -6 (multiplicity 4). State the degree of f and write f(x) in factored form.
A. Degree 10; f(x) = (x - 5)(x + 3)3(x - 9)2(x + 6)4
B. Degree 4; f(x) = (x - 5)(x + 3)(x - 9)(x + 6)
C. Degree 14; f(x) = (x - 5)2(x + 3)4(x - 9)3(x - 6)5
D. Degree 10; f(x) = (x + 5)(x - 3)3(x + 9)2(x - 6)4
