Question
If 2f(x2) + 3 f(1/x2) = x2 - 1 ∀ x ∈ R0 then f(x2) is-
Options
A.
B.
C.
D.
Solution
2f (x2) + 3f
= x2 - 1 ............(i)
replacing x by
, we get
2f
+ 3f (x2) = 
- 1 .............(ii)
Solve (i) and (ii) we get
f(x2) =
= x2 - 1 ............(i)replacing x by
, we get2f
+ 3f (x2) = - 1 .............(ii)Solve (i) and (ii) we get
f(x2) =
