Graphing rational functions according to asymptotes
Learn how to find removable discontinuities, horizontal asymptotes, and vertical asymptotes of rational functions. This video explores the specific example f(x)=(3x^2-18x-81)/(6x^2-54) before generalizing findings to all rational functions. Don't forget that not every zero of the denominator is a vertical asymptote!
