The domain of the function ( f(x)= x ) is
Options
- A( [0, 2 ] )
- B( [0, 2 ] [ 3 2 , 2 ] )
- C( [ 3 2 , 2 ] )
- D( [- 2 , 2 ] )
Correct answer
B. ( [0, 2 ] [ 3 2 , 2 ] )
Step-by-step solution
We know that, square root is defined only for non negative number Hence for ( f(x)= x ) to be defined [ 0 ] ( x ) should lies in ist and ( 4 ) th quadrant including ends of the quadrant ( x [2 n +0,2 n + 2 ] [2 n + 3 2 , 2 n +2 ] ) , where ( n Z ), for ( n=0 )
