Graph a Piece Wise Function With the Reciprocal and Square Root

The video tutorial explains how to graph the functions 1/X and the square root function, focusing on specific constraints for each. It covers graphing 1/X for X values less than zero and the square root function for X values greater than or equal to zero. The tutorial also discusses the domain and range of these functions, emphasizing the concept of infinity and discontinuity.
