Which polynomial does the model represent?

a black square, two white rods, one black rod, one white unit block and three black unit blocks are shown. (1 point)
–x³ + 2x² – 3x + 2
x² + x – 2
–x² – x + 2
–x² + x – 2

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
