question 368

Multiple Choice

Use the intermediate value theorem for polynomials to show that the polynomial function has a real zero between the
numbers given.
- $$f ( x ) = 5 x ^ { 4 } + 2 x ^ { 3 } + 10 x - 4 ; - 2 \text { and } - 1$$

• A) \(f ( - 2 ) = - 40\) and \(f ( - 1 ) = - 11\)
• B) \(\mathrm { f } ( - 2 ) = - 40\) and \(\mathrm { f } ( - 1 ) = 11\)
• C) \(\mathrm { f } ( - 2 ) = 40\) and \(f ( - 1 ) = - 11\)
• D) \(f ( - 2 ) = 41\) and \(f ( - 1 ) = - 10\)
