Polynomial Degree and End Behavior

The video tutorial explains how to determine the zeros, multiplicity, 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, calculating multiplicity based on factor exponents, and finding the polynomial's degree by analyzing the leading term. The tutorial also discusses the end behavior of polynomials, using graphs to illustrate how the function behaves as x approaches positive or negative infinity.
