Graphing y=|f(x)|


  • |f(x)| reflects any part of the original f(x) graph that was below the x-axis in the x-axis.

In this video I show you how to draw graphs of the form y=|f(x)| using the modulus function and give you three graphs to try.

Examples in the video: Sketch the following

  1. y = |x+2|
  2. y = |(x-2)(x+1)|
  3. y = |\ln (x)|
