Understanding Linear Functions

The video tutorial introduces the concept of learning mathematics without relying heavily on technology. It focuses on understanding functions, specifically linear functions, and their characteristics. The tutorial explains the role of variables and constants in functions, the importance of the function's degree, and how to identify different types of functions. It emphasizes the need for the coefficient 'a' to be non-zero in linear functions and provides examples to illustrate these concepts.
