How to describe and graph a reflection of an absolute value function

The video tutorial covers four types of functions: constant, identity, absolute value, and quadratic. It explains how to identify and graph absolute value functions, including transformations and reflections. The tutorial also discusses how multiplying by negative values affects the graph, leading to reflections over the X and Y axes. Symmetry in absolute value and quadratic functions is highlighted.
