Answer the question.Is it possible to have a polynomial function whose only zeros are 6 and i? If so, write such a function. If not, explain why.
A. Yes; P(x) = x2 - (6 - i)x - 6i is such a function. B. No; the conjugate zeros theorem requires that -i must also be a zero. C. Yes; P(x) = x2 - (6 + i)x + 6i is such a function. D. No; the conjugate zeros theorem requires that -6 and -i must also be zeros.
