### 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.

### Nth Finite Difference = Leading Coefficient * N!

We started by reviewing how to generate the equation and a sketch of the graph of polynomials in factored form.
