## How do you find a horizontal asymptote example?

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

## How do you find horizontal asymptotes in calculus?

Horizontal Asymptotes A function f(x) will have the horizontal asymptote y=L if either limx→∞f(x)=L or limx→−∞f(x)=L. Therefore, to find horizontal asymptotes, we simply evaluate the limit of the function as it approaches infinity, and again as it approaches negative infinity.

## What are the 3 different cases for finding the horizontal asymptote?

There are 3 cases to consider when determining horizontal asymptotes:

- 1) Case 1: if: degree of numerator < degree of denominator. then: horizontal asymptote: y = 0 (x-axis)
- 2) Case 2: if: degree of numerator = degree of denominator.
- 3) Case 3: if: degree of numerator > degree of denominator.

## How do you find the horizontal asymptote of a set of rules?

The three rules that horizontal asymptotes follow are based on the degree of the numerator, n, and the degree of the denominator, m.

- If n < m, the horizontal asymptote is y = 0.
- If n = m, the horizontal asymptote is y = a/b.
- If n > m, there is no horizontal asymptote.

## Can you have 3 horizontal asymptotes?

The answer is no, a function cannot have more than two horizontal asymptotes.

## How do horizontal asymptotes work?

Horizontal asymptotes are horizontal lines the graph approaches. If the degree (the largest exponent) of the denominator is bigger than the degree of the numerator, the horizontal asymptote is the x-axis (y = 0). If the degree of the numerator is bigger than the denominator, there is no horizontal asymptote.

## What is the horizontal asymptote on a graph?

An asymptote is a line that a graph approaches without touching. Similarly, horizontal asymptotes occur because y can come close to a value, but can never equal that value. Thus, f (x) = has a horizontal asymptote at y = 0.
