SV#2: Unit G Concepts 1-7 - Finding all parts and graphing a rational function

To view my video, please click on the link HERE.

This video goes over Unit G Concepts 1-7, which is finding all the key parts of a rational function. My function is f(x)=(x^3+2x^2-8x)/(x^2+5x+4), which is a slant asymptote. However, you also need to find the vertical asymptote, holes, domain, x-intercepts, and y-intercept.  More importantly, you need to graph all these parts.

In order to fully understand these concepts,  you need to make sure you follow all the steps carefully. There is a lot of work to do, so it is easy to slip up and make a mistake.  Furthermore, you need to carefully pick x values to trace on your calculator, so you can easily graph the function. Good luck!
