The value(s) of satisfying the equation [ ( ⁻¹ ⁻¹ x ) ]= , (where x R and [.] denotes the greatest integer function) is/are

Options

  1. A0
  2. B2
  3. C3 2

Correct answer

C. 3 2

Step-by-step solution

We have ( ⁻¹ ⁻¹ x )= ( ⁻¹ ) , where = ⁻¹ x= ⁻¹ 1 1+ ^2 = ⁻¹ 1 1+x^2 = 1+x^2 2+x^2 Now for all x R, 0 1+x^2 2+x^2 1 , then [ ( ⁻¹ ⁻¹ x ) ]= [ 1+x^2 2+x^2 ]=0 The equation is =0 = n , n I
