Step-by-step explanation:

ƒ(x) = 3x³ + 39x² + 39x + 27

The Rational Zeros Theorem states that, if a polynomial has any rational roots, they will have the form p/q, where p is a factor of the constant term  and q is a factor of the leading coefficient.

In your function, the constant term is 27 and the leading coefficient is 3, so

Factors of 27 = ±1, ±3, ±9, ±27

 Factors of 3 = ±1, ±3
