The function machines on the tns file allow for a variety of activities around the theme of functions. The tns files allow for various investigations, both individual and class. Examples include finding equivalent functions, predicting outputs for more complex functions and exploring inverse functions.
Before the Activity
Learners need some basic knowledge of function notation.
During the Activity
Objectives: to explore inputs and outputs of simple functions, equivalent functions and inverse functions. A video tutorial for this activity here.
After the Activity
This structure can be extended to more complex functions.
