 For \(f(x)=x^3\), compute \(\displaystyle \lim_{h\rightarrow
0}\frac{f(x+h)f(x)}{h}=\)
 For \(f(x)= (x+1)^{1}\), compute
\(\displaystyle \lim_{h\rightarrow 0}\frac{f(x+h)f(x)}{h}=\)
 Compute
\(\displaystyle \lim_{z\rightarrow x^{}} \frac{z^2x^2}{xz}=\)

Sketch the graph of a single function that is continuous except:
 at 1, where it has a removable discontinuity;
 at 2, where it has a jump discontinuity but is continuous from the right; and
 at 3, where it has an infinite discontinuity.
 Let
\[
f(x)=
\begin{cases}
{\displaystyle\frac{2x^2x15}{x3}} & \text{if \(x \lt 3\)}\\
kx1 & \text{if \(x \ge 3\)}
\end{cases}\, .
\]
Determine the value of \(k\) that will make the function \(f\) continuous at 3,
or explain why no value of \(k\) will work.

 State the Intermediate Value Theorem. Identify what are
its assumptions (hypotheses) and what are its conclusions.
 Use the Intermediate Value Theorem to show that the equation
\(x^2 =\cos(x)\) has a solution.
