Final answer:
The multiplicity of the zero x = -3 in the function P(x) = (x - 3)^2(x + 3) is 2.
Step-by-step explanation:
The multiplicity of the zero x = -3 in the function P(x) = (x - 3)^2(x + 3) is 2.
The multiplicity of a zero or root of a function refers to the number of times that zero occurs in the function.
In this case, the zero x = -3 occurs twice, once as a factor (x + 3) and once as a factor (x - 3) squared.
