This video tutorial covers graphing polynomial functions, focusing on their characteristics, types, end behavior, and attributes. It explains the concepts of relative extrema, zeros, and intervals of increase and decrease. The tutorial also delves into the multiplicity of roots and how it affects graph behavior. Finally, it provides instructions on graphing polynomials using these concepts.
