The next few questions ask you to compute the inverse of an exponential or a logarithmic function. Remember how we do this: we solve the equation $y = f(x)$ for $x$ and then switch $x$ and $y$.
The purpose of this first problem is just to make sure you understand the WeBWorK notation. You can enter the exponential with the natural base as $\exp(x)$ or $e^x$ and the natural logarithm as $\ln(x)$ or $\log(x)$. WeBWorK does not have a base 10 logarithm built into it, if you need a logarithm with a base other than $e$, let's say $a$, then enter something like $\log(x)/\log(a)$.
The inverse of the function $$f(x) = e^x$$ is
$f^{-1}(x) =$
The inverse of the function $$f(x) = \ln x$$ is
$f^{-1}(x) =$
