Answer is 1 . i guess you will understand my proof

Answer 2

Step-by-step explanation:

GIVEN :-

IF f(x) = 1 / (1-x)

TO FIND :-

derivative of f[f{f(x)}].

SOLUTION:-

f[f{f(x)}] = x ( after simplifying)

=> (d/dx) f[f{f(x)}]

= (d/dx) x

= 1

THEREFORE OPTION (C) 1

IS THE CORRECT OPTION.

HOPE THIS HELPS YOU
