Answer:

  • C. f(x) = x³ + 10x² + 7x - 18

Step-by-step explanation:

If the function has a factor of x + 9, then the function will have a zero output at x = -9

<u>Lets verify:</u>

  • A. f(-9) = (-9)³ - 8*(-9)² - 11*(-9) + 18 = -1260, No
  • B. f(-9) = (-9)³ + 10*(-9)² + 7*(-9) - 27 =  -9, No
  • C. f(-9) = (-9)³ + 10*(-9)² + 7*(-9) - 18 = 0, Yes
  • D. f(-9) = (-9)³ - 8*(-9)² + 11*(-9) + 27 = -1449, No
