Question

Use the intermediate value theorem to show that the polynomial function has a real zero between the numbers given. x Superscript 4 Baseline minus 4 x cubed minus 20 x squared plus 32 x plus 91; negative 3 and negative 2 Question content area bottom Part 1 f(negative 3)equals enter your response here (Simplify your answer. Type an integer or a fraction.) Part 2 f(negative 2)equals enter your response here (Simplify your answer. Type an integer or a fraction.) Part 3 Since f(negative 3) is positive and f(negative 2) is negative, the signs change between f(negative 3) and f(negative 2). This shows that A.Upper A zero of the polynomial lies between minus 3 and minus 2. Upper A zero of the polynomial lies between minus 3 and minus 2. B.The zeros are minus 3 and minus 2. The zeros are minus 3 and minus 2. C.The polynomial has 4 real zeros. The polynomial has 4 real zeros.
