The area (in square units) bounded by y= ⁻¹ x, y= ⁻¹ x and the Y -axis, is
Options
- A_e 4
- B_e 2
- C_e 3
- D_e 5
Correct answer
B. _e 2
Step-by-step solution
aligned & The required area =2 [ 4 - ₀^1 ⁻¹ x d x ] & = 2 -2 ₀^1 ⁻¹ x d x & . = 2 -2 [x ⁻¹ x )₀^1- ₀^1 x 1+x^2 d x ] & = 2 -2 [ 4 - 1 2 [ _e (1+x^2 ) ]₀^1 ] & = 2 - 2 + [ _e (1+x^2 ) ]₀^1 & = _e 2 aligned Hence, option (b) is correct.
