• x = 0 (multiplicity 2), x = -11 (multiplicity 1), x = 6 (multiplicity 2)

• x = 0 (multiplicity 1), x = -11 (multiplicity 2), x = 6 (multiplicity 2)

• x = 0 (multiplicity 2), x = -11 (multiplicity 2), x = 6 (multiplicity 1)

• x = 0 (multiplicity 1), x = -11 (multiplicity 1), x = 6 (multiplicity 1)

• x = -4, multiplicity 2; x = 6, multiplicity 2; x = 13, multiplicity 3

• x = -4, multiplicity 3; x = 6, multiplicity 2; x = 13, multiplicity 2

• x = -4, multiplicity 2; x = 6, multiplicity 3; x = 13, multiplicity 2

• x = -4, multiplicity 2; x = 6, multiplicity 2; x = 13, multiplicity 2

Find a polynomial f(x) of degree 3 that has the following zeros: 6, 3, -9. Leave your answer in factored form.

• f(x) = (x - 6)(x - 3)(x + 9)

• f(x) = (x + 6)(x + 3)(x - 9)

• f(x) = (x - 6)(x + 3)(x - 9)

• f(x) = (x - 6)(x - 3)(x - 9)

Find a polynomial f(x) of degree 5 that has the following zeros: 0, -4, 9 (multiplicity 2), -2. Leave your answer in factored form.

Find a polynomial f(x) of degree 4 that has the following zeros: 0, -7, 2, 5. Leave your answer in factored form.

• f(x) = x(x + 7)(x - 2)(x - 5)

• f(x) = (x - 0)(x - 7)(x - 2)(x - 5)

• f(x) = x(x - 7)(x + 2)(x + 5)

• f(x) = (x + 0)(x - 7)(x + 2)(x - 5)

Find a polynomial f(x) of degree 4 with real coefficients and the following zeros: -2 (multiplicity 2), i.
