This video tutorial covers how to graph square root and cube root functions. It begins with an introduction to the parent functions and explains how to graph them using specific values. The video then discusses the general form of these functions and how transformations such as stretching, compressing, and shifting affect their graphs. The tutorial also highlights the differences between square root and cube root functions, particularly in terms of domain and range. Finally, the video offers additional resources for students preparing for standardized tests like the ACT and SAT.
