Okay so combine like terms
10x-4x= 6x
2-8= -6
6x=-6
x= -1
Now to check:
10(-1)-2=4(-1)-8
-10-2=-4-8
-12=-12
Answer: (C) even
<u>Step-by-step explanation:</u>
A function is even when f(x) = f(-x)
A function is odd when f(-x) = -f(x)
f(x) = -2x⁴ + 3x²
f(-x) = -2(-x)⁴ + 3(-x)²
= -2x⁴ + 3x²
f(x) = f(-x) so the function is even
-f(x) = -(-2x⁴ + 3x²)
= 2x⁴ - 3x²
f(-x) ≠ -f(x) so the function is not odd.
