How do you find vertical and horizontal asymptotes

Whenever i am doing curve sketching in calculus class i find it incredibly difficult to find the vertical and horizontal asymptotes and as such i always get up to that point correct and anything from asymptotes and further wrong. Sometimes even my curve is a bit off

Finding the horizontal asymptotes of f

The question I must answer is:

"Find the horizontal asymptotes of $f(x)=\frac{\sqrt{10{x}^{2}+11}}{12x+10}$"

However, I am unsure how to find the horizontal asymptote or what this means. Can anyone explain this?

Infinite amount of vertical asymptotes

Is it possible that the graph of function has infinitely many vertical asymptotes?

I suppose, that it is not possible, because such function would not exist. But I need to prove it in a math-fashioned-way, and I'm clueless how to do it.

$F(x)=\frac{5{x}^{2}}{4{x}^{2}}+9$

Okay so when i graphed this function there are no vertical asymptotes but why is that ? Becuase if u set the denominator equal to zero then u can solve and get the vertical asymptotes

Calculating slant asymptotes of radical function

I'm trying to calculate the slant asymptotes of the function $\sqrt{{x}^{2}+2x+2}$. I've found out that the gradients of the asymptotes are 1 for $x\to +\mathrm{\infty}$ and -1 for $x\to -\mathrm{\infty}$. I've also found out that the constant of the positive asymptote is 1. Intuitively, I know the constant of the negative asymptote is -1, but I'm struggling to show it through calculation. I need to evaluate this to find it:

$\underset{x\to -\mathrm{\infty}}{lim}\sqrt{{x}^{2}+2x+2}+x$

without using l'Hôpital's rule (for the purposes of the assignment I'm not supposed to know how to use it.) I have tried rationalizing the numerator using the conjugate but I just end up with an undefined value.

Asymptotes and uniform continuity

Let $f:\mathbb{R}\to \mathbb{R}$ be a continuous function with oblique asymptotes for $x\to \pm \mathrm{\infty}$. Prove that the function is uniformly continuous.

Proof: Let . Since the function has obliquous asymptotes then

$\mathrm{\exists}M>0:|f(x)-(ax+b)|<\u03f5\phantom{\rule{1em}{0ex}}\mathrm{\forall}\phantom{\rule{thickmathspace}{0ex}}x>M$

and

$\mathrm{\exists}m>0:|f(x)-(cx+d)|<\u03f5\phantom{\rule{1em}{0ex}}\mathrm{\forall}\phantom{\rule{thickmathspace}{0ex}}x<-m$

Now, in the interval the function is uniformly continuous because of the Heine-Cantor theorem. We deal with the case $+\mathrm{\infty}$ since the other one is formally identical. We know that lines are uniformly continuous. So, using the that certainly exists for the line we have:

$\begin{array}{rl}|f(x)-f({x}_{0})|& =|f(x)-(a{x}_{0}+b)+(a{x}_{0}+b)-f({x}_{0})|\\ & \le |f(x)-(a{x}_{0}+b)|+|(a{x}_{0}+b)-f({x}_{0})|\\ & <|f(x)-(a{x}_{0}+b)|+\u03f5\end{array}$

But

$|f(x)-(a{x}_{0}+b)|\le |f(x)-(ax+b)|+|(ax+b)-(a{x}_{0}+b)|<2\u03f5$

So we are finished because if a continuous function is uniformly continuous in and , then it is uniformly continuous in .

Oblique asymptotes?

A rational function, $\frac{p(x)}{q(x)}$ has an oblique asymptote only when the degree of p(x)= degree of q(x)−1.

What "causes" the "slant" of the asymptote? Most asymptotes are caused by a function approaching an undefined value - I assume this is the same, but why (unlike others) would these asymptotes be slanted?

Why does this only work with a difference of 1 between degrees?

Identifying Asymptotes of a Hyperbola

basic hyperbolic functionHow would I find the vertical and horizontal asymptotes of a $y=\frac{1}{x}$ function algebraically? For example, $y=-\frac{2}{x+3}-1$ (as you would type into a calculator). Simply, how do I find the x and y values by looking at this equation? In other words, the middle point where the asymptotes in the picture has moved and the whole graph has been vertically stretched, where are the asymptotes now?

Do all functions with vertical asymptotes also have oblique asymptotes?

I just started learning about asymptotes in my Advanced Functions class, and as I was taking a look at all this stuff, a question came up. Do all rational functions that have vertical asymptotes also have an oblique asymptote? Or is an oblique asymptote only formed when the degree of the numerator is 1 higher than the degree of the denominator, and so only functions with a vertical asymptote with a degree of 1 can also have an oblique asymptote?

Asymptotes are straight lines that a graph approaches, but never meets. Asymptotes can be found in equations and help to answer questions about what is happening with the graph of the equation. If you are having trouble understanding asymptotes and how they relate to equations, our math site can provide the answers and help needed to make sense of them. Our expert instructors and resources can assist you in understanding asymptotes and how they relate to equations so that you can gain a better understanding of how math works.
