## How do you solve for horizontal asymptotes?

Finding Horizontal Asymptotes of Rational Functions

1. If both polynomials are the same degree, divide the coefficients of the highest degree terms.
2. If the polynomial in the numerator is a lower degree than the denominator, the x-axis (y = 0) is the horizontal asymptote.

## What does horizontal asymptote mean in a problem?

A horizontal asymptote is a horizontal line that indicates where a function flattens out as the independent variable gets very large or very small. A function may touch or pass through a horizontal asymptote.

How do you find the equation of the asymptote from an equation?

Vertical asymptotes can be found by solving the equation n(x) = 0 where n(x) is the denominator of the function ( note: this only applies if the numerator t(x) is not zero for the same x value). Find the asymptotes for the function . The graph has a vertical asymptote with the equation x = 1.

### What is horizontal asymptote example?

Certain functions, such as exponential functions, always have a horizontal asymptote. A function of the form f(x) = a (bx) + c always has a horizontal asymptote at y = c. For example, the horizontal asymptote of y = 30e–6x – 4 is: y = -4, and the horizontal asymptote of y = 5 (2x) is y = 0.

### How do you solve for vertical and horizontal asymptotes?

To find the horizontal asymptotes apply the limit x→∞ or x→ -∞. To find the vertical asymptotes apply the limit y→∞ or y→ -∞. To find the slant asymptote (if any), divide the numerator by denominator.

How do you find the asymptote of an equation example?

How to Find Horizontal Asymptotes?

1. If the degree of the polynomials both in numerator and denominator is equal, then divide the coefficients of highest degree terms to get the horizontal asymptotes.
2. If the degree of the numerator is less than the degree of the denominator, then the horizontal asymptotes will be y = 0.
