# How to write the equation of asymptotes

Aug 14, 2011 Quick tutorial on finding the equation of a vertical or horizontal asymptote. Quick tutorial on finding the equation of a vertical or horizontal asymptote.

How to Write Equations for the Aug 19, 2014 Analyse the graph to determine the equation of the rational function. Consider the following for accuracy of the result: Vertical Asymptote Horizontal Note that the domain and vertical asymptotes are" opposites". The vertical asymptotes are at 4 and 2, and the domain is everywhere but 4 Find the asymptotes for the function. To find the vertical asymptote we solve the equation x 1 0 x 1. The graph has a vertical asymptote with the equation x 1.

To find the horizontal asymptote we calculate. The numerator always takes the value 1 so the bigger x gets the smaller the fraction becomes.

To find horizontal asymptotes, we may write the function in the form of" y". You can expect to find horizontal asymptotes when you are plotting a rational function, such as: We only need the terms that will make up the equation of the line.

The slant asymptote is y x 11. As you can see in this graph of the function, the curve approaches the slant asymptote y x 11 but never crosses it: Question: Find the equations of the horizontal and vertical asymptotes for the following. Tye none if the function does not have an asymptote. Tye none if the function does not have an asymptote.

The equations of the vertical asymptotes can be found by finding the roots of q(x). Completely ignore the numerator when looking for vertical asymptotes, only the denominator matters. If you can write it in factored form, then you can tell whether the graph will be asymptotic in the same direction or in different directions by whether the Mar 10, 2008 How to write the equation of asymptotes Answer: Asymptotes are where the function does not exist, which is were you could draw a vertical line and not have it touch any part of the graph.

Vertical lines are represented by xk where k is any numerical value. For example: ycot(x) cot x does not exist at every Pi Let n any whole number so If the hyperbola is horizontal, the asymptotes are given by the line with the equation If the hyperbola is vertical, the asymptotes have the equation The fractions b a and a b are the slopes of the lines. Sal analyzes the function and determines its horizontal asymptotes, vertical asymptotes, and removable discontinuities.
