What Must Be A Factor Of The Polynomial Function F(X) Graphed On The Coordinate Plane Below? X – 6 X – 3 X + 1 X + 6. The factors of a polynomial are the quotients and the zeros of the polynomial. If a polynomial function, f (x), with rational coefficients has roots 0, 4, and , what must also be a root of f (x)?.

Substitute x=4 into the function to find y. If y=0, then f (4)=0. If a polynomial function, f (x), with rational coefficients has roots 0, 4, and , what must also be a root of f (x)?.
