Students learn how to find the outputs of a two-stage function machine.

Later, they work out the function and inputs as learning progresses.

**Differentiated Learning Objectives**

- All students should be able to use a function machine to determine an output of a linear function given its x value.
- Most students should be able to create a table of results showing x and y for any linear function.
- Some students should be able to derive a linear function given corresponding x and y values.
