Which of the following statements must be true about the polynomial function f(x)? if 1+ 13 is a root of f(x), then -1- 19 is also a root of f(x).
if 1 + 131 is a root of f(x), then 1-131 is also a root of f(x).
of 13 is a root of f(x), then -13 is also a root of f(x).
11-13 +i is a root of f(x), then 13 + 1 is also a root of f(x).
