two important features are the asymptotes and the holes of the graph. Use algebraic techniques to determine the vertical asymptotes and holes of any rational equation so that you can accurately graph it without
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...
Step 5:Determine the range by looking at the graph from bottom to top, writing any {eq}y {/eq}-values included in the graph in interval notation. Vocabulary for Finding the Intercepts, Asymptotes, Domain, and Range From the Graph of a Rational Function ...
Step 3: For each factor in the denominator, check for the same factor in the numerator and determine the type of discontinuity. If no same factors exist, then at this value of x that makes f(x) undefined, there is a vertical asymptote. If the same factor exists in the numerator,...
And if your interval length is infinity, there’s no way to determine that interval. The workaround is to turn the improper integral into a proper one and then integrate by turning the integral into a limit problem. Limits for improper integrals do not always exist; An improper integral is...
Plug the value x = 0 into the rational function and determine the value of f(x) to find the y-intercept of the function. For example, plug x = 0 into the rational function f(x) = (x^2 – 3x + 2) / (x – 1) to get the value (0 – 0 + 2) / (0 – 1), which is...
The function is undefined atx=3x=3, so there is a discontinuity at this point. To determine the type, we will need to evaluate the limit asxxapproaches 3. Step 2 Since the function has a0000form atx=3x=3, we need to find and divide out the common factors in the numerator and denomi...

Determine the horizontal asymptote, if any, of the graph of f(x) = 2x^2/(x^2 - 9). How do you find vertical asymptotes of logarithmic functions? How do you determine if a graph crosses a horizontal asymptote? How to find horizontal asymptotes with e^{-2x}? How do...
We will use these steps, definitions, and equations to determine the end behavior of rational functions in the following two examples. Example Problem 1: Determining the End Behavior of a Rational Function Determine the end behavior of the rational function. ...
