# can a function have more than one horizontal asymptote

A function can have at most two different horizontal asymptotes.

• @DavidMitra – you mean no rational function can have more than one asymptote, of course. There are plenty of functions of other types with two …
• ## Can a function have more than one asymptote?

A function can have at most two different horizontal asymptotes. A graph can approach a horizontal asymptote in many different ways; see Figure 8 in §1.6 of the text for graphical illustrations. In particular, a graph can, and often does, cross a horizontal asymptote.

## How many different vertical asymptotes can a function have?

Answer and Explanation: A rational function can have at most two horizontal asymptotes, at most one oblique asymptote, and infinitely many vertical asymptotes.

## How many horizontal asymptotes can a function have?

A function can have at most two different horizontal asymptotes. A graph can approach a horizontal asymptote in many different ways; see Figure 8 in §1.6 of the text for graphical illustrations.

## Can an even function have asymptotes?

No. A function must be defined at a point for it to be an inflection point. Functions are undefined at vertical asymptotes. How do you find the asymptotes of an equation?

## Why can a function have 2 horizontal asymptotes?

Horizontal asymptotes are very closely related to limits at infinity. f (x) = L. Notes: The definition means that the graph of f is very close to the horizontal line y = L for large (positive or negative) values of x. A function can have at most two different horizontal asymptotes.

## What is an example of a function with 2 horizontal asymptotes?

The function y = arctan(x) has two horizontal asymptotes at y=+-pi/2. The function y = arctan(x) – 1/(x^2–9) has both.

## Can rational functions have more than 2 horizontal asymptotes?

Can a rational function have two or more horizontal asymptotes? No. The numerator and denominator of a rational function are polynomials (say, in ), which are dominated by their leading powers when approaches positive or negative infinity.

## Can an equation have 2 vertical asymptotes?

More complicated rational functions may have multiple vertical asymptotes. These asymptotes are very important characteristics of the function just like holes. Both holes and vertical asymptotes occur at values that make the denominator of the function zero.

## How many different asymptotes are there?

An asymptote is a line that the graph of a function approaches as either x or y go to positive or negative infinity. There are three types of asymptotes: vertical, horizontal and oblique. That is, as approaches from either the positive or negative side, the function approaches positive or negative infinity.

## How many asymptotes of each type can a function have?

A function can have at most two oblique linear asymptotes. Furthermore, a function cannot have more than 2 asymptotes that are either horizontal or oblique linear, and then it can only have one of those on each side. This can be seen by the fact that the horizontal asymptote is equivalent to the asymptote L(x)=b.

## Can there be 3 asymptotes?

There are three kinds of asymptotes: horizontal, vertical and oblique.

## Can a function have more than 2 vertical asymptotes?

More complicated rational functions may have multiple vertical asymptotes. These asymptotes are very important characteristics of the function just like holes. Both holes and vertical asymptotes occur at values that make the denominator of the function zero.
