I apologize for the outage on the site yesterday and today. Lamar University is in Beaumont Texas and Hurricane Laura came through here and caused a brief power outage at Lamar. Things should be up and running at this point and (hopefully) will stay that way, at least until the next hurricane comes through here which seems to happen about once every 10-15 years. Note that I wouldn't be too suprised if there are brief outages over the next couple of days as they work to get everything back up and running properly. I apologize for the inconvienence.

Section 4-1 : Lines, Circles and Piecewise Functions
We’re not really going to do any graphing in this section. In fact, this section is here only to acknowledge that we’ve already looked at these equations and functions in the previous chapter.
Here are the appropriate sections to see for these.
Lines : Graphing and Functions – Lines
Circles : Graphing and Functions – Circles
Piecewise Functions : Graphing and Functions – Graphing Functions
