Did I get this practice question right?

1. Consider the following functions:
f(x)=cos(x^3-x)
h(x)=|x-3|^3
g(x)=1n(|x|+3)
s(x)=sin^3(x)

Which of the following is true?

(Points : 1)
f is even, h and s are odd.
***f and g are even, s is odd.
h and s are odd, g is even.
s is odd, f and h are even.
g and f are even, h is odd.
