Which of the following is not an odd function?
(1) f(x) = -x³
(2) f(x) = x⁵
(3) f(x) = x² – x
(4) f(x) = |x|³

Correct Answer - (4)

An odd function is a function whose value reverses in sign for a reversal in sign of its argument. i.e. f(x) = -f(-x).

Except f(x) = |x|³ all other functions mentioned in the choices change values.
