Given rational function find the vertical asymptote and hole

The video tutorial covers the concept of vertical asymptotes in rational expressions, explaining how to find them by setting the denominator equal to zero. It introduces the idea of removable and non-removable discontinuities, clarifying that removable discontinuities, or holes, occur when factors can be canceled out. The tutorial also discusses graphing lines with discontinuities and finding X and Y intercepts, emphasizing that lines do not have asymptotes but can have holes where the function is undefined.
