Decide whether the relation is a function.?
A. Function B. Not a function
Provide an appropriate response.Is it possible to have a polynomial function whose only zeros are 7 and i? If so, write such a function. If not, explain why.
A. Yes; P(x) = x2 - (7 + i)x + 7i is such a function. B. No; the conjugate zeros theorem requires that -7 and -i must also be zeros. C. No; the conjugate zeros theorem requires that -i must also be a zero. D. Yes; P(x) = x2 - (7 - i)x - 7i is such a function.
