Objective: To determine the inverse of a linear function

Instruction:

1. Type y = x in the input bar then press enter.
2. Click the REFLECT button in the tool bar. Click point A and then the line y = x.
3. Drag A. Describe the path of point A’. You can right click A’ and choose TRACE. What equation will describe the line traced by A’?
4. You can click the REFRESH icon to start your construction. You can change the given line by moving the slider, a.
5. The line traced by A’ is the inverse of the function represented by the line.  If someone will ask you what an inverse of a function is, what will you tell him/her based on this activity.
