Which of the following statements must be true about the polynomial function f(x)? If 1 StartRoot 13 EndRoot is a root of f(x), then Negative 1 minus StartRoot 13 EndRoot is also a root of f(x). If 1 13i is a root of f(x), then 1 – 13i is also a root of f(x). If 13 is a root of f(x), then –13 is also a root of f(x). If –13 i is a root of f(x), then 13 i is also a root of f(x).
