According to the Rational Root Theorem, which statement about f of x is equal to 12 x cubed minus 5 x squared plus 6 x plus 9 is true?

The Rational Root Theorem says any rational root of a polynomial written with integer coefficients must be a factor of the constant term divided by a factor of the leading coefficient. Here the constant term is 9 and the leading coefficient is 12, so any rational root must be a factor of 9 divided by a factor of 12. Therefore, the true statement is “Any rational root of f(x) is a factor of 9 divided by a factor of 12.”
