Analyzing Polynomial Functions and Behavior

The video tutorial explains how to determine the zeros, multiplicities, degree, and end behavior of a polynomial function given in factored form. It covers the process of identifying zeros by setting each factor to zero and discusses the concept of multiplicity. The tutorial also explains how to find the degree of the polynomial by identifying the term with the highest degree and calculating the end behavior based on the leading term. The video concludes with a graphical representation to verify the end behavior.
