When does a rational function pass through the horizontal …
$\begingroup$ Well after doing some example questions, the line of the function sometimes passed the horizontal asymptote. Just graph the function I gave as an example (the answer key shows it passed through the asymptote.) $\endgroup$ –
Constructing a rational function from its asymptotes
Jun 1, 2016 · $(b) \frac{2x}{(x-3)}$. Same reasoning for vertical asymptote, but for horizontal asymptote, when the degree of the denominator and the numerator is the same, we divide the coefficient of the leading term in the numerator with that in the denominator, in this case $\frac{2}{1} = 2$ $(c) \frac{(x-4)}{(x-1)(x+1)}$. Same reasoning for vertical ...
Why can't a rational function have both, a horizontal and an …
Sep 20, 2016 · Horizontal and oblique asymptotes describe the behavior of the function "at infinity". If there is a horizontal asymptote, then the behavior at infinity is that the function is getting ever closer to a certain constant. If there is an oblique asymptote, then the function is getting ever closer to a line which is going to infinity.
Why Can A Graph Pass Through Its Horizontal Asymptote?
Jul 21, 2018 · How close does the line need to get to the asymptote for it to be considered approaching? And lastly, if a line in a graph gets very close to an "asymptote" on one side of the "asymptote", then veers completely away from the "asymptote" after passing through it, can this "asymptote" still be considered an asymptote?
If a rational function has no horizontal asymptote, does it then …
Aug 28, 2017 · This is assuming that the function is in a fractional form where the the degree of the numerator is higher than the degree of the denominator.
Why do the "rules" of horizontal asymptotes of rational functions …
Jan 15, 2019 · Rule 2) If the numerator and denominator have equal degrees, then the horizontal asymptote will be a ratio of their leading coefficients. Rule 3) If the degree of the numerator is exactly one more than the degree of the denominator, then the oblique asymptote is found by dividing the numerator by the denominator.
Family of functions with two horizontal asymptotes
I think what you're looking for is a form of logistic function, such as. f(x) = 2 1 +ex − 1. edit: For your specific criteria with y1 and y2: f(x) = y1 −y2 1 +ex +y2. edit 2: For comparison of my answer to the other two answers: dashed/black: 2 1+ex − 1; blue: −2 πarctan x; red: − x x2+1√. Share.

How to find the asymptotes of a square root function?
Mar 10, 2016 · We can substitute u = y − x u = y − x and v = y + x v = y + x, and the resulting equation is. uv = 3 u v = 3. which has asymptotes u = 0 u = 0 and v = 0 v = 0. Substituting the old variables back in tells us that the asymptotes are y = −x y = − x and y = x y = x. Share. Cite.
