Asymptote Calculator – Graph Asymptotes and Equations

This tool helps you calculate the vertical, horizontal, and oblique asymptotes of any given function.

How to Use the Asymptote Calculator

Enter a function in the form of a fraction (e.g. (x^2-4)/(x-2)) and the calculator will determine if there is a vertical asymptote and/or horizontal asymptote.

Steps:

  1. Enter the function `f(x)` with `x` as the variable (e.g., (x^2-4)/(x-2) ).
  2. Enter the `x-value` for finding the vertical asymptote.
  3. Click on “Calculate” to find the asymptotes.

How It Calculates the Results:

The script parses the entered function and evaluates if there are any vertical asymptotes at the specified `x-value`. If the function is a rational function (i.e., a fraction of polynomial expressions), it checks if making the denominator zero will find the vertical asymptote. The script also checks if the function has a horizontal or slant asymptote.

Limitations:

This calculator currently evaluates vertical asymptotes for rational functions only. It does not consider cases where there could be oblique/slant asymptotes or holes in the graph. Additionally, the evaluation of horizontal asymptotes is limited to simple polynomials and rational functions.

Use Cases for This Calculator
