A horizontal asymptote is a y-value on a graph which a function approaches but does not actually reach. Here is a simple graphical example where the graphed function approaches, but never quite reaches, y=0y=0. In fact, no matter how far you zoom out on this graph, it still won't ...
Examples: Find the horizontal asymptote of each rational function:First we must compare the degrees of the polynomials. Both the numerator and denominator are 2nd degree polynomials. Since they are the same degree, we must divide the coefficients of the highest terms. In the numerator, the ...
The function y=1xy=1x is a very simple asymptotic function. As x approaches positive infinity, y gets really close to 0. But, it never actually gets to zero. The curve of this function will look something like this, with a horizontal asymptote at y=0y=0: Let's take a more complica...
Then, determine the degree of the function in the denominator. Step 5: Use your horizontal asymptote rules to determine the location of your horizontal asymptote. This should be written in the form of an equation, as y=... How to Find the Asymptotes of a Rational Function ...
An asymptote is a line that the graph of a function approaches but never touches. Rational functions contain asymptotes, as seen in this example: In this example, there is a vertical asymptote at x = 3 and a horizontal asymptote at y = 1. The curves approach these asymptotes but never cr...
Horizontal Asymptote:A horizontal asymptote is a horizontal line (y=b, wherebis a constant) that the graph of a function approaches, but does not touch. To find the horizontal asymptote of a function, we use the following rules: Rule 1: If the degree of the denominator i...
Check the degrees of the polynomials for the numerator and denominator. If the denominator is of greater degree, then there is a horizontal asymptote, and it's the x-axis. If the degrees of the numerator and denominator are the same, then there is a horizontal asymptote, and it's the ...
