Which of the following expressions is not in its simplest form? m + 3 n + 6 mn - 4
9 m + 7 n - 6 mn + 4
7 m - 9 n - 6 mn + 4
9 m + 7 n - 6 mn + 4 m

it's both, now can you answer my most recent question?

maya’s expression will generate the wrong sum because she violated the commutative property.

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
