Section 3.1 Class Notes
Linear Functions and Their Properties
Framing Thoughts for this Section
•
We’ve already studied equations of lines and graphs of lines in chapter 1, so much of this
material will seem familiar.
•
The main difference is that we will reexamine these ideas using the language and notation of
functions.
•
In addition, we will think about how some of the general properties of functions we studied in
chapter 2 apply to linear functions and we will consider applications that involve linear
functions.
Framing Thoughts for the Rest of the Course
•
This chapter is where we start examining individual families of functions.
•
The “routine” will become familiar to you.
For functions in this family:
o
What should you expect to see in a formula, a table of values, a graph, and a
verbal description?
o
What is the domain, the range?
o
What properties should you expect to see?
