Which of the following statements must be true about the polynomial function f(x)?
A
If is a root of f(x), then is also a root of f(x).
B
If 1 + 13i is a root of f(x), then 1 – 13i is also a root of f(x).C
If 13 is a root of f(x), then –13 is also a root of f(x).D
If –13 + i is a root of f(x), then 13 + i is also a root of f(x).
