Why Some Rational Functions Have No Vertical Asymptote

The video tutorial explores rational expressions that do not have vertical asymptotes, addressing common student misconceptions. It provides three examples: simplifying rational expressions, identifying removable discontinuities, and using complex numbers to explain the absence of vertical asymptotes. The tutorial emphasizes the importance of understanding when a function is undefined and how this relates to vertical asymptotes.
