Transformations of Quadratic and Absolute Value Functions

This video tutorial covers transformations of parent functions, focusing on absolute value and quadratic transformations. It explains the roles of variables a, b, h, and k in these transformations, providing examples and practice problems. The video also distinguishes between quadratic and absolute value functions, highlighting their unique characteristics and transformation rules.
