This video tutorial covers absolute value functions, starting with their basic properties and graphing techniques. It explains how to graph these functions using a table of values, focusing on the vertex and symmetry. The tutorial advances to graphing with transformations and handling cases where the vertex involves fractions. Finally, it explores piecewise functions that include absolute values and linear functions, detailing how to graph them effectively.

What is the notation for the absolute value function?

• f(x) = x + 2

• f(x) = 1/x

• f(x) = |x|

• f(x) = x^2
