Use the intermediate value theorem to show that the polynomial function has a real zero between the numbers given. f(x)=4x2-2x-6; 1 and 2 What is 1(1)? (Simplify your answer. Type an integer or a fraction.) 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. OA. Since 1(1) and 1(2) are opposite in sign, there exists at least one zero between 1 and 2. OB. Since 1(2) is greater than f(1), the function is increasing and so there must be one real zero between 1 and 2. k
