Creating piece wise functions using CBR system

Activity Overview

In this lesson, students will use the CBR ranger to model walking distance over time. They will walk away from the sensor, back towards the sensor and finally away from the sensor over an interval of 10 seconds. The result should be 3 lines. They will then use algebra skills to get the three equations, restrict their domains and finally put the equations and restricted domains into the calculator to model the three different lines.
