Given:
To find:
The odd function.
Solution:
If f(-x) = -f(x), then the function is odd.
If f(-x) = f(x), then the function is even.
Option A:
Substitute x = -x
≠ - f(x)
It is not odd function.
Option B:
Substitute x = -x
(Since
)
≠ - f(x)
It is not odd function.
Option C:
Substitute x = -x
≠ - f(x)
It is not odd function.
Option D:
Substitute x = -x
It is odd function.
Therefore, f(x) = -x is an odd function.
