f\left( x \right)

is defined on

\left[ {0,\;1} \right],

then the domain of definition of

f\left( {\tan x} \right)

is

View answer and explanation

Correct option: A

\left[ {n\;\pi ,n\;\pi + \pi /4} \right],\;n \in Z

Option A (

[n \pi ,n \pi + \pi /4],\;n \in Z

) is correct because it defines the interval where

0 \le \tan x \le 1

.
