Question 104483: Hello,
I have the following multiple choice question:
Find an nth degree polynomial function with real coefficients satisfying the given conditions.
n = 3; - 4 and i are zeros; f(-3) = 60

A) f(x) = 6 + 24 + 6x + 24

B)
f(x) = -6 - 24 + 6x + 24
C)
f(x) = 6 + 24 - 6x - 24

D)
f(x) = -6 - 24 - 6x - 24
I'm not sure if I'm supposed to substitute the values into the multiple choices to see which one works out. Regardless, I would like to find the answer on my own without having to plug the values in. Could you help me? I looked in my algebra book but I couldn't find a section for this. I would greately appreciate it if someone could give me some direction.
Thank you,
EJ
