 # Graph Absolute Value Functions

Videos and lessons with examples and solutions to help High School students learn how to graph functions expressed symbolically and show key features of the graph, by hand in simple cases and using technology for more complicated cases.

Graphs of square root, cube root, and piecewise-defined functions, including step functions and absolute value functions.

Graphing Absolute Value Functions
This video looks at graphing simple absolute value functions by hand. It includes three examples.

Transforming Absolute Value Functions
This video looks at transforming absolute value functions. It includes five examples, including horizontal shifts, vertical shifts, reflections, and stretches and compressions.
Graphing Absolute Value Functions
This tutorial demonstrates two methods for graphing linear absolute value functions. The first half of the video utilizes function translations of a base function to create the sketch of the graph. The second half demonstrates making the graph using a table of values.
