Use the Intermediate Value Theorem for Polynomials to Show That $$f ( x ) = 6 x ^ { 3 } - 10 x + 7 ; - 2 \text { and } - 1$$

Use the intermediate value theorem for polynomials to show that the polynomial function has a real zero between the
numbers given.
- $$f ( x ) = 6 x ^ { 3 } - 10 x + 7 ; - 2 \text { and } - 1$$

A) $f ( - 2 ) = - 21$ and $f ( - 1 ) = 11$
B) $f ( - 2 ) = - 20$ and $f ( - 1 ) = 12$
C) $f ( - 2 ) = 21$ and $f ( - 1 ) = - 11$
D) $f ( - 2 ) = 21$ and $f ( - 1 ) = 11$
