Answer:
Option (A)
Explanation:
If a function 'f' is an odd function,
f(-x) = -f(x)
If a function 'f' is an even function,
f(-x) = f(x)
In this question given function is,
f(x) =
To check the given function is odd or even,
f(-x) =
=
Therefore, from the definition of even and odd functions,
Function 'f' is an odd function.
Option (A) will be the correct option.
