This document discusses the rational roots theorem and how to use it to find rational roots of a polynomial function. It provides an example of using the rational roots theorem to find the roots of the polynomial function f(x)=3x^3 - 4x^2 - 5x + 2. The procedure involves listing possible numerators and denominators, testing candidates, and using synthetic division to factor the polynomial into linear and quadratic factors until all rational roots are found.
