BEST explanation how to determine domain algebraically

The video tutorial explains how to determine the domain and range of functions, focusing on restrictions such as division by zero and taking the square root of negative numbers. It covers scenarios where expressions are in the denominator or under a radical, and how these affect the domain. The tutorial also discusses the domain of sine and cosine functions, emphasizing their continuity in both positive and negative directions.
