See the coversheet for instructions and the point value of each problem.
 Simplify and cancel so that you can plug in the given value
without dividing by 0. Then plug in the value.
 For \(x=2\), \( \frac{x^2+x6}{x2}=\)
 For \(x=4\), \( \frac{\sqrt{x}2}{x4}=\)
 For \(h=0\), \( \frac{(x+h)^2 x^2}{h}=\)
 For \(h=0\), \( \frac{(x+h)^{1}  x^{1}}{h}=\)
 For \(h=0\) and \(f(x)=2x^2\), \(\frac{f(x+h) f(x)}{h}=\)

Sketch the graph of a single function \(f\) that:
 has \(\displaystyle \lim_{x\rightarrow 0}f(x)=1\)
 has \(\displaystyle \lim_{x\rightarrow 3^}f(x)=2\)
 has \(\displaystyle \lim_{x\rightarrow 3^+}f(x)=2\)
 has \(f(0) = 1\)
 has \(f(3) = 1\)
 A machinist is required to
manufacture a circular metal disk with area \(1000\,
\mathrm{cm}^2\).
 What radius produces such a disc?
 If the machinist is allowed an error tolerance of \(\pm
3\, \mathrm{cm}^2\) in the area of the disk, how close to the
ideal radius you found above must the machinist control the
radius?
 In terms of the \(\epsilon\), \(\delta\) definition of
\(\displaystyle \lim_{x\rightarrow a} f(x)=L\), what is
\(x\)? What is \(a\)? What is \(L\)? What value of
\(\epsilon\) is given? What is the corresponding value of
\(\delta\)?
