" Use the Intermediate Value Theorem to show that the polynomial f(x) = x + x - 3x + 66 has a real zero between - 5 and - 1. . . . Select the correct choice below and fill in the answer boxes to complete your choice. O A. Because f(x) is a polynomial with f( - 5) = 0, the function has a real zero between - 5 and - 1. O C. Because f(x) is a polynomial with f( - 5) = > 0 and f( - 1) = > 0, the function has a real zero between - 5 and - 1. O D. Because f(x) is a polynomial with f( - 5) = > 0 and f( - 1) =
