Determine the end behavior of a graph as well as the zeros and degree

The video tutorial explains how to determine the end behavior of polynomial functions using the leading coefficient test and graph analysis. It covers estimating zeros and determining whether a polynomial is of odd or even degree based on the number of zeros. The tutorial emphasizes understanding the behavior of the graph as x approaches positive and negative infinity.
