-$$f ( x ) = - 7 ( x - 2 ) ^ { 2 } - 8$$
A) $( 2 , - 8 )$
B) $( - 8,2 )$
C) $( - 2 , - 8 )$
D) $( - 7 , - 2 )$

The given quadratic function is in vertex form, where the vertex is at the point (h,k) given by the equation f(x) = a(x-h)^2 + k. Therefore, we can read off the vertex as (2,-8) where h=2 and k=-8. Thus, the answer is choice A.
