How to Identify a Linear Function

The video tutorial addresses a standardized math test question about identifying linear functions. It begins by explaining the characteristics of a linear function, specifically focusing on the variable having an exponent of 1. The tutorial then analyzes several equations, distinguishing between linear, quadratic, and exponential functions. Finally, it identifies the correct equation that represents a linear function, emphasizing the importance of recognizing the exponent of the variable.
