What is end behavior of a polynomial

The video tutorial explains the concept of end behavior in graphs, particularly focusing on continuous graphs in a Cartesian coordinate system. It discusses how graphs extend to infinity and how end behavior can be predicted using the leading coefficient test. The tutorial highlights that for polynomials with even degrees and positive leading coefficients, the graph will rise to both the left and right. The video concludes with a summary of these concepts.
