माना `f` एक फलन है जो निम्न प्रकार से परिभाषित है `f:(0,e^((-3)/(2))]to[(-1)/(4),oo),f(x)=(lnx)^(2)+3lnx+2`, तो `f^(-1)(x)` बराबर है :
(i) `log((-3+sqrt(4x+1))/(2))` (ii) `log((-3-sqrt(4x+1))/(2))`
(iii) `e^((-3+sqrt(4x+1))/(2))` (iv) `e^((-3-sqrt(4x+1))/(2))`

A

`log((-3+sqrt(4x+1))/(2))`

B

`log((-3-sqrt(4x+1))/(2))`

C

`e^((-3+sqrt(4x+1))/(2))`

D

`e^((-3-sqrt(4x+1))/(2))`
