How to label the discontinuities and domain of rational function

The video tutorial covers various factoring techniques, including factoring the greatest common factor (GCF) and the difference of squares. It explains how to simplify expressions and identify discontinuities such as holes and asymptotes. The tutorial also discusses determining the domain of a function with discontinuities, providing a comprehensive understanding of these mathematical concepts.
