Sketch the Graphs of Inverse Functions $f ( x ) = \frac { x } { 3 } , f ^ { - 1 } ( x ) = 3 x$

Sketch the graphs of inverse functions $f ( x ) = \frac { x } { 3 } , f ^ { - 1 } ( x ) = 3 x$ in the same coordinate plane and show that the graphs are reflections of each other in the line $y = x$

A) $\begin{array} { l l l l } x & - 3 & 0 & 3 \\f ( x ) & - 1 & 0 & 1\end{array}$ $\begin{array} { l l l l } x & - 1 & 0 & 1 \\f ^ { - 1 } ( x ) & - 3 & 0 & 3\end{array}$
B) $\begin{array} { l l l l } x & - 2 & 0 & 3 \\f ( x ) & - 1 & 0 & 1\end{array}$ $\begin{array} { l l l l } x & - 1 & 0 & 1 \\f ^ { - 1 } ( x ) & - 3 & 0 & 3\end{array}$
C) $\begin{array} { l l l l } x & - 3 & 0 & 3 \\f ( x ) & - 1 & 0 & 1\end{array}$ $\begin{array} { l l l l } x & - 1 & 0 & 1 \\f ^ { - 1 } ( x ) & - 3 & 2 & 3\end{array}$
D) $\begin{array} { l l l l } x & - 3 & 0 & 0 \\f ( x ) & - 1 & 0 & 1\end{array}$ $\begin{array} { l l l l } x & - 1 & 0 & 1 \\f ^ { - 1 } ( x ) & - 3 & 0 & 3\end{array}$
E) $\begin{array} { l l l l } x & - 3 & 0 & 3 \\f ( x ) & - 1 & 0 & 1\end{array}$ $\begin{array} { l l l l } x & - 1 & 0 & 1 \\f ^ { - 1 } ( x ) & - 2 & 0 & 3\end{array}$
