How to find the end behavior of a polynomial in factored form

The video tutorial covers polynomial expansion and simplification, focusing on multiplying polynomials and determining end behavior. The teacher explains the process of expanding terms and emphasizes the importance of the leading term in understanding polynomial behavior. The class concludes with homework instructions, focusing on understanding polynomial behavior rather than extrema.

How does the graph behave as it goes to the left and right according to the teacher's explanation?

What is the homework assignment related to extrema, and what should the students focus on instead?
