Determine whether f(x)=3x^4-x^2 is even or odd.
-----------------
For any integer value of x, it's even.
If x is even, both terms are even. The difference of 2 even numbers is even.
Same for odd, the difference of 2 odd numbers is even.

x^4 will always give you a positive number for an answer
work it out using a -2 or a +2 for x
