The video tutorial introduces polynomial functions, focusing on their characteristics, such as degree and leading coefficient. It explains how these factors influence the end behavior of polynomial graphs, including the number of possible x-intercepts. Examples and non-examples of polynomial functions are provided, and generalizations about their behavior are discussed. The lesson concludes with a summary and assignment instructions.
