intermediate value theorem

Use the intermediate value theorem to show that the polynomial has a real zero between the given integers. f(x) = 4x - 4x - 4; between 1 and 7 Select the correct choice below and, if necessary, fill in the answer box(es) within your choice. (Simplify your answers.) O A. Because f(x) is a polynomial with f(1) = > 0 and f(7) = > 0, the function has a real zero between 1 and 7 O B. Because f(x) is a polynomial with f(1) = > 0 and f(7) = 0, the function has a real zero between 1 and 7 O D. Because f(x) is a polynomial with f(1) =
