    Re: 202 AP Calculus Inverse of e^x

    the graph is close, but no cigar.

    $f(1)=e \implies f^{-1}(e) =1$

    however, if $f^{-1}(x)=\dfrac{1}{2}\ln{x}$, then $ f^{-1}(e)

    I would be inclined to think that "side area" means "area of the sides" which is what what skeeter calculated.

    Re: 202 AP Calculus Inverse of e^x

    The inverse of $f(x)=e^x$ is $f^{-1}(x) = \ln{x}$

    ... there is an obvious mistake in the answer choices.

    Maybe a typo? $f(x)

    202 AP Calculus Inverse of e^x

    If $f^{-1}(x)$ is the inverse of $f(x)=e^x$, then $f^{-1}(x)=$


    $a. \ln\dfrac{2}{x}$
    $b. \ln \dfrac{x}{2}$
    $c. \dfrac{1}{2}\ln
