Use the Intermediate Value Theorem for Polynomials to Show That $f ( x ) = 3 x ^ { 3 } - 3 x + 8 ; - 2$

Use the intermediate value theorem for polynomials to show that the polynomial function has a real zero between the numbers given.
- $f ( x ) = 3 x ^ { 3 } - 3 x + 8 ; - 2$ and $- 1$

A) $f ( - 2 ) = - 10$ and $f ( - 1 ) = 8$
B) $f ( - 2 ) = - 9$ and $f ( - 1 ) = 9$
C) $f ( - 2 ) = 10$ and $f ( - 1 ) = - 8$
D) $f ( - 2 ) = 10$ and $f ( - 1 ) = 8$
