Question 239

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) =2x37x2+4x+8;1f ( x ) = 2 x ^ { 3 } - 7 x ^ { 2 } + 4 x + 8 ; - 1 and 0


A) f(1) =5f ( - 1 ) = 5 and f(0) =8f ( 0 ) = - 8
B) f(1) =4f ( - 1 ) = - 4 and f(0) =9f ( 0 ) = 9
C) f(1) =5f ( - 1 ) = - 5 and f(0) =8f ( 0 ) = 8
D) f(1) =5f ( - 1 ) = 5 and f(0) =8f ( 0 ) = 8
