How do you find a vertical asymptote given 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.
Does 1 /( x 2 1 have a vertical asymptote?
Since 1×2−1 1 x 2 – 1 → −∞ as x → 1 from the left and 1×2−1 1 x 2 – 1 → ∞ as x → 1 from the right, then x=1 is a vertical asymptote.
How do I find the asymptote?
The horizontal asymptote of a rational function can be determined by looking at the degrees of the numerator and denominator.
- Degree of numerator is less than degree of denominator: horizontal asymptote at y = 0.
- Degree of numerator is greater than degree of denominator by one: no horizontal asymptote; slant asymptote.

How do you find Asymptotes?
How do you find vertical and horizontal asymptotes?
While vertical asymptotes describe the behavior of a graph as the output gets very large or very small, horizontal asymptotes help describe the behavior of a graph as the input gets very large or very small. Recall that a polynomial’s end behavior will mirror that of the leading term.
How to find the vertical asymptote of a graph?
Find the vertical asymptotes of the graph of k(x) = 5+2×2 2−x−x2 k ( x) = 5 + 2 x 2 2 − x − x 2. First, factor the numerator and denominator. To find the vertical asymptotes, we determine where this function will be undefined by setting the denominator equal to zero:
How to find the asymptotes of f ( x )?
Determine the horizontal asymptotes of f(x) = 3 + 4 x, if any. Sometimes the values of a function f become arbitrarily large as x → ∞ (or as x → −∞). In this case, we write lim x → ∞f(x) = ∞ (or lim x → −∞f(x) = ∞).
How many times can a function cross an asymptote?
In fact, a function may cross a horizontal asymptote an unlimited number of times. For example, the function f(x) = ( cosx) x + 1 shown in Figure 4.42 intersects the horizontal asymptote y = 1 an infinite number of times as it oscillates around the asymptote with ever-decreasing amplitude.
Which is greater degree of numerator or degree of Asymptote?
Degree of numerator is less than degree of denominator: horizontal asymptote at y = 0. Degree of numerator is greater than degree of denominator by one: no horizontal asymptote; slant asymptote. Degree of numerator is equal to degree of denominator: horizontal asymptote at ratio of leading coefficients.
