Answer 1

\(\large \color{black}{\begin{align} & \normalsize \text{Find the inverse of } \hspace{.33em}\\~\\
& f(t)=\dfrac{10^{t}-10^{-t}}{10^{t}+10^{-t}} \hspace{.33em}\\~\\~\\~\\
& a.)\ \dfrac12 \times \log_{10} \left(\dfrac{1-t}{1+t}\right) \hspace{.33em}\\~\\
& b.)\ \dfrac12 \times \log_{10} \left(\dfrac{t-1}{t+1}\right) \hspace{.33em}\\~\\
& c.)\ \dfrac12 \times \log_{10} (2t-1) \hspace{.33em}\\~\\
& d.)\ \text{none of these} \hspace{.33em}\\~\\
\end{align}}\)

i think its d.)
