Characteristics and Concepts of Polynomials

The video tutorial covers the third part of Unit C, focusing on polynomial functions. It explains the characteristics of polynomials, including examples and non-examples, and introduces the concept of standard form. The tutorial also demonstrates solving polynomial problems using direct and synthetic substitution methods. Students are given practice problems and homework assignments to reinforce their understanding.
