Options
- A0
- B2( 2 -1)
- C2 -1
- D2( 2 +1)
Correct answer
B. 2( 2 -1)
Step-by-step solution
aligned & ₀^ / 2 | x- x| d x & = ₀^ / 4 -( x- x) d x + _ / 4 ^ / 2 -( x- x) d x aligned aligned & aligned = & -[- x- x]₀^ / 4 +[- x- x]_ / 4 ^ / 2 = & - [- 1 2 - 1 2 +1 ] + [-0-1+ ( 1 2 + 1 2 ) ] = & 2 -1-1+ 2 = & 2( 2 -1) aligned aligned
