Solving Polynomial and Rational Applications

We started class by watching these videos and students asked questions about the videos.

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.

Solving Polynomial Inequalities

 
We started by solving some linear inequalities and graphing our solution on a number line.
