Group Quiz Answers

Here's the answer key to the group quiz.  Keep in mind that some folks answered in a different form than I did, but were still correct.  I choose to answer in the simplest form because I find that I make fewer errors that way.

 

Classwork 4/1

Here's the classwork from today.  I would like you to finish the work to be checked tomorrow.  I would skip #19 as it ends up being a cubic equation and is generally mean to math students.

 

3/26-27 Homework

I will be checking iii and vi on the Graphing Rational Equations WS 3 for Friday.

Classwork 3/26-7

Here are the answers to today's classwork.

Keep in mind the following tips for gathering information about a rational function:

The domain excludes all of the undefined or "bad" x values.
The range excludes (possibly) horizontal asymptotes and "holes"
The end behavior is what happens to y values as x goes to +/- infinity
Horizontal asymptotes are defined by end behavior
Vertical asymptotes are defined by undefined x values that aren't canceled
Y-intercepts are found at f(0)
Zeroes are the defined values where the numerator = 0
Holes are defined by the undefined x values that are canceled

Here's some of the work we've looked at regarding graphs of rational equations.

 

 

 

Quiz Review for Friday

Here are the answers to the review we started in class.  Your quiz on Friday will cover Variations, Adding/Subtracting Rational Functions, and Multiplying/Dividing Rational Functions.

 

3/17 HW and Classwork

We talked about adding and subtracting rational functions.  The homework is on Page 588(2-4, 7-15, 23, 25)  You can find today's notes and the answers to the homework below.  The homework will be checked for effort.
