How to determine the VA of a function

The video tutorial explains vertical asymptotes as discontinuities in functions, particularly in rational functions where the denominator cannot be zero. To find vertical asymptotes, set the denominator equal to zero. An example is provided where the vertical asymptote is calculated to be 1, indicating where the function is undefined. The tutorial emphasizes the importance of understanding vertical asymptotes in analyzing function behavior.
