I know It's probably an easy question but I don't know remember how to do it.

Show the work to determine if the relation is even, odd, or neither.


a ) f(x) = 2x^2 - 7
b) f(x) = -4x^3 - 2x
c) f(x) = 4x^2 - 4x + 4

If f(-x) = f(x), for any x, the function is even.
If f(-x) = -f(x), for any x, the function is odd.
It can be neither.
Try substituting -x for x and see what you get.

Hint: Two of the functions are neither even nor odd.

Only c) is neither even nor odd.
