Up to this point we have been solving quadratic inequalities. The technique involving sign charts extends to solving polynomial inequalities of higher degree.

Rational inequalities are solved using the same technique. The only difference is in the critical numbers. It turns out that the

Use open dots for all of the critical numbers when a strict inequality is involved.
