Graph Characteristics and Function Ranges

The video tutorial by Amal Kumar covers piecewise functions, focusing on determining the domain and range. The function H(x) is analyzed in three parts, with a detailed explanation of its domain as all real numbers. The range is found by sketching the function, which is emphasized as a reliable method. The video concludes with an exercise to practice sketching and analyzing another piecewise function.
