What is the range of function f(x) = {x}+{-x}
[0,1)
(-1,1)
{0,1}
[0,1]
As we have learned
Fractional part function -
When Greatest Integer Function
- wherein
f(x) = {x}+{-x}
If x Z f(x) = 0
If x doesn't belong to Z ; then x= Z+k
f(x) = {Z+K}+ {-Z-K}
= K+1-K=1
Option 1)
[0,1)
Option 2)

Option 3)
{0,1}
Option 4)
[0,1]
