Answer the questions. \begin{enumerate} \item Given that \(\sqrt{13}\) is about \(3.6\), what can you say about \(2^{\sqrt{13}}\) without using a calculator? \item How do you find the number \(e\) with a calculator? \item What makes the number \(e\) special as a base for an exponential function? \item For an exponential function \(y=b^x\): (i) What are the \(x\)- and \(y\)-intercepts? (ii) What are the asymptotes? (iii) What are domain and range? \item What is the main difference between the graphs of \(y=e^x\) and \(y=e^{-x}\)? \end{enumerate}
