The range of the function f(x)= [x],- 4 < x < 4 , where [x] denotes the greatest integer x , is

Options

  1. A0
  2. B0,-1
  3. C0, 1
  4. D0,- 1

Correct answer

D. 0,- 1

Step-by-step solution

Given, f(x)= [x],- 4 < x < 4 array ll Clearly, & 0=0 and & [ 4 ]= [ 3.14 4 ]=0 array aligned & x [0, 4 ], [x]=0 & x [- 4 , 0 ],[x]=-1 & [x]= (-1)=- 1 aligned So, the range of f(x) is 0,- 1 .
