    Classify the following functions as one of the types that we have discussed:
    \begin{enumerate}
      \item $f(x) = 5^x$ \pause\quad is an exponential function
    \pause
      \item $g(x) = x^5$ \pause\quad is a power function, a polynomial of degree $5$, a rational function and an algebraic function.
    \pause
      \item $h(x) = \frac{1+x}{1-\sqrt{x}}$ \pause\quad is an algebraic function. 
    \pause
      \item $u(t) = 1-t+5t^4$ \pause\quad is a polynomial of degree $4$, a rational function and an algebraic function.
    \pause
      \item $v(x) = x^{-3}$ \pause\quad is a power function, a rational function and an algebraic function.
    \pause
      \item $p(x) = x^{-\frac{1}{3}}$ \pause\quad is a power function, and an algebraic function.
    \pause
      \item $z(x) = \frac{1+x}{3+x^2}$ \pause\quad is a rational function, and algebraic function. 
    \end{enumerate}
