My mathematics book is very poor on it's explinations, so can someone look at my logic and tell me if I understand this correctly. I'm looking for a yes or no.

Code:`f(x)=x^3 - x`

f(-x)=(-x)^3 - (-x)

=(-1)^3 (x)^3 + x

=(-1)(x)^3 + x // since f(x) != f(-x) then not even

=(-x)^3 + x

=(-1)(x^3 - x) //odd

=-f(x)

f(-x) = -f(x) Odd
