How to find vertical asymptotes Rational Functions and Vertical Asymptotes: Rational functions are functions that have a variable in the denominator. That is, they are of the formr(x) =f(x) /g(x), whereg(x) is not the zero function. Because rational functions have a variable in the den...
To find a vertical asymptote, first write the function you wish to determine the asymptote of. Most likely, this function will be a rational function, where the variable x is included somewhere in the denominator. As a rule, when the denominator of a rational function approaches zero, it has...

Whereas vertical asymptotes are found by locating the zeroes of the denominator, the horizontal asymptote is found by comparing degrees and perhaps doing some division. Let's look at an example of finding horizontal asymptotes: Find the horizontal asymptote of the following function: ...
Learn how to find asymptotes both algebraically and graphically. Discover how to calculate horizontal asymptotes and find equations of vertical and slant asymptotes. Related to this Question How do you find the horizontal asymptote of 4^x - 2?
Step 2:Find all vertical asymptotes. A vertical asymptote is a vertical linex=cthat the graph of the function cannot touch. The graph will instead get closer to this line, but either go up or down infinitely and never touch the line. ...
From what I know about rational functions and vertical asymptotes (of which, this function has one), I know that the graph will go forever upward and forever downward, so the range is indeed everything other than y = 0. I'll use this to find the domain and range of my inverse. Here...
graph of the function crosses the x- and y-axes. Find the y-intercept of a rational function as you would for any other type of function: plug in x = 0 and solve. Find the x-intercepts by factoring the numerator. Remember to exclude holes and vertical asymptotes when finding the ...
For graphing functions, we need to take care of domain, range, asymptotes, and holes. Also, we need to know at least two to three points on each part of the curve for graphing the function.
How do you find the slope of asymptotes of a hyperbola? What is the equation of a line that is parallel to y = -4x + 2 and goes through the point (-4, 9)? Find the equation of the tangent line to the graph of y = (2x + 3)/(3x - 2) at the point (1,5) using the qu...
