How To Find Horizontal Asymptotes

3rd June 2024

In this article, we’ll discuss how to find horizontal asymptotes for a given function. This particular part in physics may be challenging for a lot of students. First, we need to understand what a horizontal asymptote is. A horizontal asymptote is a line that has no slope on it. This means that from any x value on the graph of our function y = f(x), it will take the same amount of steps to get from x = 0 to x = 1 (the origin). If you can’t see this immediately, try drawing the graph in two stages: one where you start at some point on your chosen axis (e.g., y = 2x + 5) and another where you draw an arrow pointing up when moving horizontally across the axes (e.g., y = 5). 

What is an Asymptote? 

An asymptote is a line that connects two points on a graph. It is said to be a line that a graph will approach or approach but never touch. This is because their rates of change are very close to zero. An example of an asymptote is x=1. As the x-value gets closer to 1, the y-value gets closer and closer to zero. Another example is y=x^2. As the x-value gets larger, the y-value gets larger and larger. However, as the x-value gets closer to infinity, the y-value gets closer to zero. An asymptote is important to know and can be used in many ways. It can help you with calculus, algebra, and even statistics. This is because it allows you to visualize how things get closer or farther away from another point.

How to find horizontal asymptotes:

First, determine whether the function is even

First, determine whether the function is even. If it is an odd function and its derivative has a positive value at y=0, then you can conclude that there is a horizontal asymptote at that point. In this case we would say that y=0 is a vertical asymptote for our original equation (y=-1).

On the other hand if your original function has no derivative at all when it approaches zero from above or below then you know for sure that there isn’t any horizontal asymptotes for your original equation!

Make sure the function is in fraction form, with the top and bottom in separate expressions

To find the horizontal asymptotes, you must be sure that the function is in fraction form. The top and bottom expressions should be separated by an equals sign (if they are not, then you can’t find the horizontal asymptote). In addition to being sure that your functions are in fraction form, make sure that your top and bottom expressions have no variables on either side of them (to avoid confusion). You don’t want to confuse yourself!

If the denominator has a horizontal asymptote at y=0, then it is an odd function

If the denominator has a horizontal asymptote at y=0, then it is an odd function. However, if the denominator doesn’t have a horizontal asymptote at y=0, then it is an even function (and vice versa).

If the denominator has no horizontal asymptote at y=0, then it is an even function

In case the denominator has no horizontal asymptote at y=0, then it is an even function. If the denominator does have a horizontal asymptote at y=0, then it is an odd function.

Find horizontal asymptotes of the numerator by dividing its degree by the denominator’s degree

To find horizontal asymptotes of a function, you must first divide its degree by the denominator’s degree. The degree of the numerator is the degree of the numerator minus one and so on for any other terms in your equation. If your function has only one term, then its degrees can be added together to get a total number that’s less than or equal to zero (if it were positive).

To find horizontal asymptotes using this method:

Use these results to determine whether or not there are any horizontal asymptotes for the whole function. The best way to find the horizontal asymptotes of a function is by using [the function’s derivative] If the numerator’s degree (the power) is less than or equal to the denominator’s degree (the exponent), then there will be no horizontal asymptote at y=0, since all points on that line would be equal in size. If they’re not equal in size, then we can say that there is a horizontal asymptote at y=0 because it represents where we’d get if we were able to draw an infinitely long line through those points on our graph and keep going forever without ever hitting anything else except for infinity itself!

But if you’re trying to find out where a function’s horizontal asymptotes will be, here’s how to do it:

If the function is even, then it has a horizontal asymptote at y=0. For example, if you have a function f(x)=2x+4 and x=0, then f(0) will be 2 and there’s no y-value for which you can get back to 0. If the function is odd, then it will have one or more horizontal asymptotes at y=0 (or some other value). For example:

  • If x > 0: f(x) = 1/(1 – x^2) = 1/(1 – .25 + .75^2), so there are two values where this function approaches zero; these are when x = -1 or -2

Conclusion

Asymptotes, essential in calculus, represent the limits our curves approach but never quite reach, akin to the line x = 4. These lines or planes guide us as functions change, showing rates converging towards zero or infinity. For instance, in y = x^2, as x = 5, y = 25, illustrating rapid growth. Understanding asymptotes is key for navigating complex functions and their behavior.
