as "x" approaches infinity and "y" approaches 0 for the function "y=1/x" — "y=0" is the horizontal asymptote. You can save time in finding horizontal asymptotes by using your TI-83 to create a table of "x" and "y" values of the function, and observing trends in ...
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...
this is not always the case: other functions break off at a point of discontinuity, or turn off and never make it past a certain point on the graph. Vertical and horizontal asymptotes are straight lines that define the value that a given function approaches if it does...
Find the vertical asymptotes of the function: \frac{x^2+2}{4x-5x^2} Find the vertical asymptotes of the function f(x) = \frac{x^4 - 4x^3 -x^2 - 4}{2x^3-2} Find the vertical asymptotes of the function y = \frac{8x^2 + 1}{9x - 8x^2} Find all vertical asymptotes of ...
Domain and Range:The domain of a function is the set of all possible inputs {eq}x {/eq} for the function. The range of a function is the set of all possible outputs {eq}y {/eq}. We will use these steps and definitions to find the intercepts, asymptot...
The slant (or oblique) asymptote for that rational function is a straight (but not horizontal or vertical) line that shows where the graph goes, off to the sides.How do you find the slant (or oblique) asymptote?To find the slant asymptote, do the long division of the numerator by the ...
How do you find the vertical asymptotes of a polynomial? Explain how to locate vertical asymptotes. Find all vertical asymptotes of the function Find the vertical asymptotes of the function y = \frac{8x^2 + 1}{9x - 8x^2} Find the vertical asymptotes of the function: \frac{x^2+2}{4x...
Find the horizontal asymptote of the following function: First, notice that the denominator is a sum of squares, so it doesn't factor and has no real zeroes. In other words, this rational function has no vertical asymptotes. So we're okay on that front. ...
A rational equation contains a fraction with a polynomial in both the numerator and denominator -- for example; the equation y = (x - 2) / (x^2 - x - 2). When graphing rational equations, two important features are the asymptotes and the holes of the gra
