You appear to be on a device with a "narrow" screen width (i.e. you are probably on a mobile phone). Due to the nature of the mathematics on this site it is best views in landscape mode. If your device is not in landscape mode many of the equations will run off the side of your device (should be able to scroll to see them) and some of the menu items will be cut off due to the narrow screen width.
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
