This video tutorial covers graphing radical equations, starting with the parent function y = √x. It explains how to determine the domain and range, and explores the effects of reflections over the x and y axes. The tutorial also discusses vertical and horizontal shifts, using points for accurate graph sketches, and analyzing domain and range in transformed functions. Advanced transformations, including the impact of negative signs and complex shifts, are also covered.
