Asymptote Calculator

Vertical asymptote are known as vertical lines they corresponds to the zero of the denominator were it has an rational functions. Distance between the asymptote and graph becomes zero as the graph gets close to the line. The vertical graph occurs where the rational function for value x, for which the denominator should be 0 and numerator should not be equal to zero. Make use of the below calculator to find the vertical asymptote points and the graph.

Method 1:

The line x = a is called a Vertical Asymptote of the curve y = f(x) if at least one of the following statements is true.

Vertical Asymptote

Method 2:

For rational functions, vertical asymptotes are vertical lines that correspond to the zeroes points of the denominator. Given rational function, f(x) Write f(x) in reduced form f(x) - c is a factor in the denominator then x = c is the vertical asymptote.


Consider an equation 2x^2+4x+1 / x^2-16

Step 1 :

We need to equal the denominator to 0.
= x^2-16 = 0
= x^2 - 4^2 = 0
= (x-4) (x+4)
Hence, x = 4, x = -4
