Absolute Value and Quadratic Functions

This video tutorial explores the absolute value of quadratic functions. It begins with an introduction to the concept and proceeds to find the X and Y intercepts of a quadratic function. The tutorial then demonstrates how to graph the quadratic function and its absolute value, focusing on the transformation and reflection of the graph. Finally, it explains the domain, range, and piecewise function representation of the absolute value of the quadratic function.
