Polynomial Functions and Their Properties

This video tutorial by Anil Kumar covers polynomial functions, focusing on solving ten questions related to x-intercepts, factoring, writing quartic functions, and applying the factor and remainder theorems. It also includes graphing polynomials and a bonus section on factoring an unfactorable expression. The tutorial is part of an advanced functions curriculum and is suitable for precalculus and IB math students.
