Answer: Choice D
Both functions are even
--------------------------------------------------------------------------
If you graph both f(x) and g(x), you'll see that there is symmetry along the vertical y axis. This is visual proof that the functions are even. For algebraic proof, note how all the exponents are even. For the constant terms, there is a hidden x^0 term so the exponent is even there as well.
