There is a function f(x) that is differentiable over the whole set of real numbers. Let g(x) be the inverse of this function.

obviously something went wrong

#

But i cant perceive it

#

Since f(4)=4, I can use g'(4)=1/f'(4), but I want to know why the above solution is wrong.

if g(x) = 1/f(x), then g'(x) is not 1/f'(x)

#

Even if the inverse function of f(x) is g(x)?

"Inverse" is different from "reciprocal"
