Module 7: Absolute Value and Reciprocal Functions

Can you read the words in the graphic shown? Now try reading it upside down. (You may need to print the page first.) An ambigram is a word graphic that can be read from more than one perspective. In the image, you may have noticed that the word “math” is the same when read upside down! Ambigrams are commonly used in the tattooing industry for this special property. Indeed, a design that can be read by both the onlooker as well as the tattooed person has a practical appeal.
In this lesson you will discover how the graphs of absolute value functions are similar to ambigrams. Besides exploring their graphs, you will also consider an alternate way of expressing absolute value functions using a special type of notation.
Here are some of the words you will want to define in Module 7 Glossary Terms in this lesson:
- critical point
- piecewise notation
