Question
Hi
i have a question on determining if a equation is even odd like
X raise to the 4 plus x square plus 6?
x square root 2 plus x square?

Answer
x^4 + x^2 + 6

If x is odd, x^4 and x^2 are both odd, so the sum is even.
When 6 is added, it is still even.

If x is even, x^4 and x^2 are both even, so the sum is even.

Either way, that expression is even.


x√2+x²: for this problem, I will assme it is really x√(2+x²).
This is never even or odd, for there 2+x² is never a whole integer.
