Which of the following real valued functions is/are not even functions?
f(x) = x - [x], where [x] denotes the greatest integer less than or equal to x.
C.
D.
f(x) = x - [x], where [x] denotes the greatest integer less than or equal to x.
we know that,
if f(-x) = f(x), then function is even and if
f(- x) = - f(x), then function is odd.
So, f(x) is even.
So, f(x) is even.
So, f(x) is not even.
So, f(x) is not even.
