Which of the following is not an odd function?
Choose the correct choice from the following answers:
A) f(x) = -x3	B) f(x) = x5	C) f(x) = x2 - x	D) f(x) = |x|3	E) None of these
Solution:   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.   Answer f(x) = |x|3
