For x ∈ R – {0, 1}, let f 1 (x) = 
, f 2 (x) = 1 – x and f 3 (x) = 
be three given functions. If a function, J(x) satisfies 
(x) = f 3 (x) is equal to :
A
f 3 (x)
B
f 1 (x)
C
f 3 (x)
D
f 2 (x)
Text Solution
Verified by ExpertsThe correct answer is:
C
Sol. f 2 (Jo(f 1 (x))) = f 3 (x)
⇒ 1 – J (f 1 (x)) = f 3 (x)
⇒ 1 – J 
= 
⇒ J 
= 1 – 
= – 
⇒ J(x) = 
= 
⇒ J(x) = f 3 (x)
