It's difficult for us to automatically graphasymptotes for a variety of reasons. However, we hope tohave this feature in the future! In the meantime, it's possible tocreate an asymptote manually. Start by graphing the equationof the asymptote on a separate expressionline.
Subsequently, one may also ask, how do you find asymptotes of a graph?
Asymptotes. An asymptote is a line that agraph approaches without touching. Similarly, horizontalasymptotes occur because y can come close to a value, butcan never equal that value. In the previous graph, there isno value of x for which y = 0 ( ≠ 0), but as x gets very largeor very small, y comes close to 0.
Considering this, how do you find Asymptotes?
Finding Horizontal Asymptotes of RationalFunctions
- If both polynomials are the same degree, divide thecoefficients of the highest degree terms.
- If the polynomial in the numerator is a lower degree than thedenominator, the x-axis (y = 0) is the horizontal asymptote.
The three rules that horizontal asymptotes follow are basedon the degree of the numerator, n, and the degree of thedenominator, 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.
