Function Notation

Published on 12/01/2011

Activity Overview

Investigate and understand the symbolic language in the notation of functions used in mathematics.

Objectives

  • Students will understand function notation and the distinction between an input value x, a function f, and a function output f(x)
  • Students will determine the rule for a function machine after using several inputs and observing the outputs.
  • Students will use function notation in problems.

Vocabulary

  • Function
  • Input
  • Output

About the Lesson

This lesson allows students to freely vary the input to a process (represented by a "machine" diagram) and observe the resulting output. As a result, students will:
