If f(x)= array ll [x] & if -3 < x -1 |x| & if -1 < x < 1 |[x]| & if 1 x < 3 array . then the set (x: f(x) 0) is equal to

Options

  1. A(-1,3)
  2. B[-1,3)
  3. C(-1,3]
  4. D[-1,3)

Correct answer

A. (-1,3)

Step-by-step solution

Given that, aligned & f(x)= array l [x] if -3 < x -1 |x| if -1 < x < 1 |[x]| if 1 x < 3 array . & When -3 < x -1, f(x)=[x] & f(x) < 0 aligned
