To find horizontal asymptotes of a function y = f(x), we use the formulas y = lim ₓ→∞ f(x) and y = lim ₓ→ -∞. If any of these limits results in a non-real number, then just ignore that limit.
6 Αυγ 2024 · In a rational function, an equation with a ratio of 2 polynomials, an asymptote is a line that curves closely toward the HA. The HA helps you see the end behavior of a rational function. In this article, we'll show you how to find the horizontal asymptote and interpret the results of your findings.
10 Νοε 2020 · Horizontal asymptotes can take on a variety of forms. Figure 1.36(a) shows that \(f(x) = x/(x^2+1)\) has a horizontal asymptote of \(y=0\), where 0 is approached from both above and below. Figure 1.36(b) shows that \(f(x) =x/\sqrt{x^2+1}\) has two horizontal asymptotes; one at \(y=1\) and the other at \(y=-1\).
20 Δεκ 2023 · How to Find a Horizontal Asymptote. We follow the steps below to determine the horizontal asymptote of any function y = f (x), where x → ± ∞. We find the value of lim x → ∞ f (x) We do the same for lim x → − ∞ f (x) If one (or both) values is a real number b, then the horizontal asymptote is given as y = b.
