1) its number 2. 30x^7y^4
y = x² - 12x + 8
First step is to move the 8 to the other side by subtract 8 from both sides. This gives you:
y - 8 = x² - 12x
Now we complete the square. Divide the b term (in this case 12) by 2, then square the result. You will then add that square to both sides. This gives you:
y - 8 + 36 = x² - 12x + 36
Combine like terms and factor:
y + 28 = (x - 6)²
y = (x - 6)² - 28. Option A should be your answer.

It is neither.
To be even, f(x) must equal f(-x).
If you substitute -x for x, you'd get
y = (-x)^2 - 2(-x) -8
y = x^2 +2x -8
This is not the same as the original, so this is not even.
To be odd, f(x) must equal -f(-x).
If you take the -x substitution from the last step and then multiply it by -1, you'd have:
y = -1 (x^2 +2x -8)
y = -x^2 -2x +8
This is not the same as the original either.
The function is neither even nor odd.
