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.
