Answer:
see explanation
Step-by-step explanation:
If f(x) and g(x) are the inverses of each other, then
f(g(x)) = g(f(x)) = x
f(g(x)) = f(x - ) = x -
+
= x
g(f(x)) = g(x + ) = x +
-
= x
Hence f(x) and g(x) are the inverse of each other
If I've read this correctly, it looks like this.
If that is correct, then the first step is to put the top part of the denominator over 3x
The next part is to flip a three tier fraction. I'm afraid I have to show what happens. My latex is not that strong.
