Which of the following is a polynomial with roots 2, 3i, and -3i? a. f(x) = x^3 - 2x^2 + 6x - 9 b. f(x) = x^3 - 6x ^2 + 9x - 18 c. f(x) = x^3 - 6x^2 + 18x - 2 d. f(x) = x^3 + 2x^2 + 9x - 18

Since the roots are 2,3i, and -3i, you can write it as

(x-2)(x-3i)(x+3i)=(x-2)(x^2+9)=x^3-2x^2+9x-18.

the correct answer would be c

1332.

this is because to get from 333 to 999 you multiply by 3, and you should do the same to the number of hours.

therefore you would do 444*3=1332
