What does multiplicity mean in terms of the roots of an equations?

• To clone a polynomial

• How many times a particular number is a zero for a given polynomial.

• how many times a polynomial function can be multiplied

• how many end behaviors a polynomial has

State the zeros of the polynomial (include multiplicity):
f(x) = x(x+3)²(x - 2)

• x = 0, 3, 2
• x = 0, -3 (multiplicity of 2), 2
• -3, 2
• 0, 2 (multiplicity of 3)
