Find the slant asymptote of $$ f(x)=\frac{2 x^{2}-7 x-1}{x-2} $$ (Section \(2.6, \text { Example } 8)\)
Use a graphing utility to graph two periods of the function. $$y=-2 \cos \left(2 \pi x-\frac{\pi}{2}\right)$$
Determine whether each statement makes sense or does not make sense, and explain your reasoning. After using the four-step procedure to graph \(y=-\cot \left(x+\frac{\pi}{4}\right),\) I checked my graph by verifying it was the graph of \(y=\cot x\) shifted left \(\frac{\pi}{4}\) unit and reflected about the \(x\) -axis.
The toll to a bridge costs \(\$ 8.00 .\) Commuters who frequently use the bridge have the option of purchasing a monthly discount pass for \(\$ 36.00 .\) With the discount pass, the toll is reduced to \(\$ 5.00 .\) For how many bridge crossings per month will the cost without the discount pass be the same as the cost with pass? What will be the monthly cost for each option? (Section P.8, Example 3)
Solve: \(\quad 8^{x+5}=4^{x-1}\) (Section 3.4, Example 1)
