Result
The calculator will display the asymptotes corresponding to the entered function (if they exist).
What Are Asymptotes?
An asymptote is a line that a given function approaches (but never reaches) when the input variable approaches a certain value. Essentially, asymptotes provide boundaries that functions adhere to without crossing or touching. They come in a variety of forms and provide insight into the long-term behavior of functions.
There are three types of asymptotes:
- Vertical Asymptote: If the function approaches infinity (or negative infinity) as $$$x$$$ approaches $$$a$$$, $$$x=a$$$ is a vertical asymptote. The function is undefined at this point. An example is the function $$$f(x)=\frac{1}{x}$$$, which has a vertical asymptote at $$$x=0$$$.
- Horizontal Asymptote: If the function's value approaches $$$b$$$ as $$$x$$$ goes to positive or negative infinity, $$$y=b$$$ is a horizontal asymptote. For instance, the function $$$f(x)=\frac{1}{x}$$$ has a horizontal asymptote $$$y=0$$$.
- Oblique (or Slant) Asymptote: This occurs when the graph of a function approaches a non-horizontal straight line as $$$x$$$ goes to positive or negative infinity. They typically appear in rational functions where the degree of the polynomial in the numerator is one more than that in the denominator. For example, the function $$$f(x)=\frac{x^2}{x+1}$$$ has an oblique asymptote $$$y=x-1$$$.
It is very important to understand that although a function's curve may appear to touch or get extremely close to its asymptotes, it never actually intersects or reaches them. The concept of asymptotes is fundamental in calculus and helps to understand the behavior of functions and their graphs.

FAQ
What is an asymptote?
An asymptote is a line that a given function approaches (when the function's variable approaches a certain value) but does not intersect.
How does the Asymptote Calculator work?
Simply input your function into the designated field and the calculator will determine the vertical, horizontal, or oblique asymptotes for that function.
What types of functions can I input?
The calculator is optimized for rational functions but can also handle a wide range of other functions to determine their asymptotes.
Why doesn't every function have a horizontal asymptote?
Horizontal asymptotes relate to the function's behavior as $$$x$$$ approaches positive or negative infinity. If the function doesn't stabilize at a particular value (or range of values) as $$$x$$$ grows without bounds, it might not have a horizontal asymptote.
