Domain of Rational Functions

The video tutorial explains how to find the domain of rational functions by identifying discontinuities, which are values that make the denominator zero. It provides examples of single and multiple discontinuities and discusses removable discontinuities, emphasizing the importance of setting the denominator equal to zero to find undefined values.
