If 0 < x < / 2 , then

Options

  1. A2 > x x
  2. B2 < x x
  3. Cx x >1
  4. D2 < x x

Correct answer

B. 2 < x x

Step-by-step solution

0 0 and u(x) is decreasing. u(x) < u(0)=0 . Thus, f^ (x) < 0 f(x) decreasing function also. 0 < x < 2 aligned & f ( 2 ) < f(x) < f(0) & 2 < x x < 0 aligned Option (b) is correct.
