PAPPC LESSON 3.4

Your task today is to find the domain of a rational function.
You must also know how to find the vertical, horizontal, and slant asymptotes of a rational function.

To determine the domain, you must find the values that cause the denominator to = zero. These values are NOT in the domain. It may help you to "see" the domain if you sketch a number line, put open circles for undefined values, and shade the line for values that are in the domain. Use your number line as an aid in writing the interval(s) that make up the domain.

Use you class notes to study vertical, horiz., and slant asymptotes. If you have any questions, please ask for help online.

Bonus Question: Worth 2 point on Friday's quiz. e-mail your answer to tsnipes@mscs.k12.al.us Your e-mail must be posted before 8 am on Thurs. Sept. 11, 2008

1. Explain how to find the holes and vertical asymptotes of a rational function.
2. Explain why a polynomial function will never have any vertical asymptotes or
holes."

I understand the concept of everything, but the execution of finding holes and asymptotes sometimes confuse me. Just exactly how early are you gonna be at the school?

It is 7:08 and I have been here since 7 am. Don't worry. I will do a lot more teaching in class today.
