Comparing Polynomial and Exponential Growth

The video tutorial explains how to compare polynomial and exponential growth by examining function values in tables and graphs. It reviews the end behavior of both polynomial and exponential functions as x approaches infinity, highlighting that both types of functions grow towards positive infinity. The tutorial uses examples, tables, and graphs to demonstrate that while polynomial functions may initially grow faster, exponential functions eventually surpass them. The video concludes by emphasizing that exponential growth will always overtake polynomial growth in the long run.

What happens to the y-values of a polynomial function as x approaches infinity, assuming a positive leading coefficient?
