Use the Intermediate Value Theorem for Polynomials to Show That $f ( x ) = x ^ { 4 } - 9 x ^ { 2 } + 18 ; 1.7$

question 204

Multiple Choice

Use the intermediate value theorem for polynomials to show that the polynomial function has a real zero between the
numbers given.
- $f ( x ) = x ^ { 4 } - 9 x ^ { 2 } + 18 ; 1.7$ and $1.8$

• A) \(f ( 1.7 ) = 0.3421\) and \(f ( 1.8 ) = 0.6624\)
• B) \(f ( 1.7 ) = 0.3421\) and \(f ( 1.8 ) = - 0.6624\)
• C) \(f ( 1.7 ) = - 0.3421\) and \(f ( 1.8 ) = - 0.6624\)
• D) \(f ( 1.7 ) = 0.6579\) and \(f ( 1.8 ) = - 0.6624\)
