Use the Intermediate Value Theorem to Determine Whether the Polynomial f(x)=3x45x3+25x245x18f ( x ) = 3 x ^ { 4 } - 5 x ^ { 3 } + 25 x ^ { 2 } - 45 x - 18

Question 42

Multiple Choice

Use the Intermediate Value Theorem to determine whether the polynomial function has a zero in the given interval.
- f(x) =3x45x3+25x245x18f ( x ) = 3 x ^ { 4 } - 5 x ^ { 3 } + 25 x ^ { 2 } - 45 x - 18


A) f(x) =(3x+1) (x2) (x+3) (x3) f ( x ) = ( 3 x + 1 ) ( x - 2 ) ( x + 3 ) ( x - 3 )
B) f(x) =(3x+1) (x2) (x+3i) (x3i) f ( x ) = ( 3 x + 1 ) ( x - 2 ) ( x + 3 i ) ( x - 3 i )
C) f(x) =(3x1) (x+2) (x+3i) (x3i) f ( x ) = ( 3 x - 1 ) ( x + 2 ) ( x + 3 i ) ( x - 3 i )
D) f(x) =(3x1) (x+2) (x+3) (x3) f ( x ) = ( 3 x - 1 ) ( x + 2 ) ( x + 3 ) ( x - 3 )
