Remember that 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 ...
Horizontal Horizontal asymptotes tell you about the farendsof the graph, or the extremities, ±∞. Because of this, graphs can cross a horizontal asymptote. A rational function will have a horizontal asymptote when the degree of the denominator is equal to the degree of the numerator. Why is ...

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.Horizontal Asymptotes and Slant Asymptotes of Rational Functions15 related questions found How do you identify a horizontal ...
A General Note: Horizontal Asymptotes of Rational Functions 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=0y=0 Degree of numerator is ...
Students will determine the domains of rational functions. Students will be able to predict behavior of rational function graphs (including intercepts and asymptotes) before graphing. Students will also show proficiency in recognizing discontinuities and their types. Students will use this information to ...

Asymptotes of Rational Functions | Formula, Types & Examples from Chapter 12 / Lesson 5 45K This lesson explores rational polynomial functions. It also covers how to find the different asymptotes of these functions. Related to this QuestionWhat...
So We'll look at some very big values for x, some values of x very far from the origin. From the above graphs, we know the lines y=0 and y=1 are the horizontal asymptotes of rational functions. y=(x+2)/(x^2+1).gsp As we can see in the table of values and the graph, ...
