Absolute Value

Activity Overview

Worksheet designed to help students explore the absolute value function focusing specifically on notation such as f(|x|) and |f(x)|.


Students need to be able to quickly identify how the absolute value function has transformed a function and also the reverse, identify the way the absolute function has been used given a transformed graph.


  • Absolute Value
  • Transformation
  • Reflection: x-axis
  • Reflection: y-axis

About the Lesson

Students are provided with a number of functions that help illustrate the geometric transformations associated with the absolute value function. Particular focus is drawn to notation such as f(|x|) and |f(x)|. Students can see the original function and the resulting absolute value function making it easier to draw comparisons.
