If a function \(f\) represents a system that varies in time, the existence of \(\lim _{t \rightarrow \infty} f(t)\) means that the system reaches a steady state (or equilibrium). For the following systems, determine if a steady state exists and give the steady-state value. The amount of drug (in milligrams) in the blood after an IV tube is inserted is \(m(t)=200\left(1-2^{-t}\right)\).
A sequence is an infinite, ordered list of numbers that is often defined by a function. For example, the sequence \(\\{2,4,6,8, \ldots\\}\) is specified by the function \(f(n)=2 n\), where \(n=1,2,3, \ldots .\) The limit of such a sequence is \(\lim _{n \rightarrow \infty} f(n)\), provided the limit exists. All the limit laws for limits at infinity may be applied to limits of sequences. Find the limit of the following sequences, or state that the limit does not exist. \(\left\\{2, \frac{3}{4}, \frac{4}{9}, \frac{5}{16}, \ldots\right\\},\) which is defined by \(f(n)=\frac{n+1}{n^{2}},\) for \(n=1,2,3, \ldots\)
a. Evaluate \(\lim _{x \rightarrow \infty} f(x)\) and \(\lim _{x \rightarrow-\infty} f(x),\) and then identify any horizontal asymptotes. b. Find the vertical asymptotes. For each vertical asymptote \(x=a\), evaluate \(\lim _{x \rightarrow a^{-}} f(x)\) and \(\lim _{x \rightarrow a^{+}} f(x)\). $$f(x)=16 x^{2}\left(4 x^{2}-\sqrt{16 x^{4}+1}\right)$$
We say that \(\lim _{x \rightarrow a^{+}} f(x)=-\infty\) if for any negative
number \(N,\) there exists \(\delta>0\) such that $$f(x)
Use the following definitions.
Assume fexists for all \(x\) near a with \(x>\) a. We say that the limit of \(f(x)\)
as \(x\) approaches a from the right of a is \(L\) and write \(\lim _{x \rightarrow
a^{+}} f(x)=L,\) if for any \(\varepsilon>0\) there exists \(\delta>0\) such that
$$ |f(x)-L|<\varepsilon \quad \text { whenever } \quad 0
