Very poorly posted; not clear.
(1) Are "F" and "f" the same? (If not, the question makes no sense at all.)
(2) Are the "f-1" and "F-1" supposed to be inverse functions, "f^(-1)" and "F^(-1)"?
If F and f are the same, and those are supposed to be inverse functions (the only way the post makes sense), then
f(f^(-1)(x)) = x
and
f^(-1)(f(x) = x
So each of those functions is equivalent to the identity function, g(x)=x.
And the inverse of the identity function is the identity function.
ANSWER: The inverse of each of the given functions is the identity function, g(x)=x.
