Which of the following is a polynomial with roots 4, 2i, and −2i?
f(x) = x3 − 4x2 + 8x − 4
f(x) = x3 − 8x2 + 16x − 4
f(x) = x3 − 4x2 + 4x − 16
f(x) = x3 − 4x2 + 8x − 16

good luck!

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
