Question

The graphs of $y={\sinh }^{-1}\left(x\right)$ is the mirror image of that of $y=\sinh \left(x\right)$ along which of the following lines?

• A. $y=0$
• B. $x=0$
• C. $y=-x$
• D. $y=x$

Answer 1

The correct option is D $y=x$

$y=\sinh x$ and $y={\sinh }^{-1}x$ can be drawn as shown in the figure. It is clearly seen that the mirror image of $y=x$
