A vertical asymptote with a rational function occurs when there is division by zero. For example, with f (x) = \frac {3x} {2x -1} , f (x) = 2x−13x, the denominator of 2x-1 2x −1 is 0 when x = \frac {1} {2} , x = 21, so the function has a vertical asymptote at \frac {1} {2} . 21.

Vertical asymptotes can be identified by looking for the vertical gaps or areas of the graph that the lines avoid. For example, in the graph below, we see two curving lines that are avoiding the line of x = − 2. Therefore, the vertical asymptote is x = − 2.

They are handy in showing how different parts of the function influence the graph. The three types of asymptotes are vertical asymptote, horizontal asymptote, and oblique asymptote. The best place to start is with vertical asymptotes. What are vertical asymptotes? Rational functions work like fractions.

Vertical asymptotes occur where the denominator of a rational function approaches zero. A rational function cannot cross a vertical asymptote because it would be dividing by zero. Horizontal asymptotes occur when the x -values get very large in the positive or negative direction. Horizontal asymptotes can be crossed.
