Solving Rational Inequalities
We solved rational inequalities by creating a number line and placing the roots and the vertical asymptotes on the number line. We can then find the sign of one interval using a test point and then figure out the signs in all the other intervals using what we know about odd and even roots and odd and even vertical asymptotes.
