MCQ
${\sin ^{ - 1}}\left[ {{{\log }_3}\left( {\frac{x}{3}} \right)} \right]$ નો પ્રદેશ મેળવો.
  • $[1, 9]$
  • B
    $[-1, 9]$
  • C
    $[-9, 1]$
  • D
    $[-9, -1]$

Answer

Correct option: A.
$[1, 9]$
$y = {\sin ^{ - 1}}\left[ {{{\log }_3}\left( {\frac{x}{3}} \right)} \right]$
$ \Rightarrow - 1 \le {\log _3}\left( {\frac{x}{3}} \right) \le 1$
$ \Rightarrow \frac{1}{3} \le \frac{x}{3} \le 3$
$ \Rightarrow 1 \le x \le 9$
$ \Rightarrow x \in [1,\,9]$.
