QUICK ANSWER…

B

DETAILS…

To resolve this, all we have to do is to substitute x = -2 into the polynomial y = x³ – x + 3

y = (-2)³ – (-2) + 3

y = -8 + 2 + 3

y = -3

Now for the right answer to the above question:

  1. Option A is incorrect.
  2. Option B is correct.
  3. C is incorrect.
  4. D is not the correct answer.
