Lesson: Function Machines Mathematics

Join Nagwa Classes

Attend live Mathematics sessions on Nagwa Classes to learn more about this topic from an expert teacher!

In this lesson, we will learn how to use function machines to find the function rule and evaluate direct and inverse operations.

Students will be able to

use one-step function machines to
- input a number into a function machine and calculate an output,
- work out the function rule from a set of inputs and outputs,
- calculate an input from the function rule and the output,
use two-step function machines to
- input a number into a function machine and calculate an output,
- calculate an input from the function rules and the output,
solve more complex problems, such as replacing a two-step function machine with a one-step function machine, choosing the correct function rules for a two-step function machine from a set of multiple choices, or calculating an output for a three-step function machine.
