Q) Determine whether g(x) = x/8 has an inverse function.

Going through the steps that I have in this book, I get the following:

Is this correct?

Interchange \(\displaystyle x,y\) to get
\(\displaystyle x=y/8\)
\(\displaystyle y=8x\) as the inverse function.

cool, exchange x and y then, that was the step I was missing.

Thanks.
