( _ - / 4 ^ II / 4 d x 1+ 2 x ) is equal to
Options
- A( 12 )
- B( 11 )
- C( 04 )
- D( 00 )
Correct answer
B. ( 11 )
Step-by-step solution
Given that ( I= _ - 4 ^ 4 d x 1+ 2 x ) We know that, ( 1+ 2 x=2 ² x ) So, ( I= _ - 4 ^ 4 d x 2 ² x = 1 2 _ - 4 ^ 4 ² x d x ) We know that if ( f ( x ) ) is even function then, [ array l _ -a ^ a f(x) d x=2 ₀^ a f(x) d x So, I= 1 2 2 ₀^ 4 ² x d x= ₀^ 4 ² x d x =[ x]₀^ r 4 = 4 - 0=1 array ]
