For the value of 2 (x) 1- ^2(x) to be positive, find values of x , such that x (0, 2 )

Options

  1. A(0, 3 )
  2. B(0, 6 )
  3. C(0, 4 )
  4. D(0, 8 )

Correct answer

C. (0, 4 )

Step-by-step solution

Given, aligned & 2 x 1- ^2 x >0 & 2 x>0 aligned Since, 0 < 2 x < 2 [ 2 x . is the in .Q₁ ] array ll & 0 < x < 4 & 0 < x < 4 as x (0, 2 ) array Hence, option (3) is correct.
