Question 12 Of 24 This question: 1 point(s) possible Submit test Use the intermediate value theorem to show that the polynomial function has a real zero between the numbers given. What is f(1)? (Simplify your answer. Type an integer or a fraction.) f(x) = 4x - 2x - 8; 1 and 2 What is f(2)? (Simplify your answer. Type an integer or a fraction.) Choose the correct statement below that explains why the given polynomial has a zero between 1 and 2, according to the intermediate value theorem. A. Since f(1) and f(2) are opposite in sign, there exists at least one zero between 1 and 2. O B. Since f(2) is greater than f(1), the function is increasing and so there must be one real zero between 1 and 2
