I'M GIVING BRAINLIEST. I just need help with the equation, you don't have to solve it.
it needs to be an inequality.
if you don't know what an inequality look at the other picture.

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
