A) $x = 2 ; ( - 8 , - 4 )$
B) $x = 8 ; ( 8 , - 4 )$
C) $( - 8 , - 4 ) ; x = - 8$
D) $x = 8 ; ( - 8 , - 4 )$

The axis of symmetry for a parabola in the form $y = a(x - h)^2 + k$ is $x = h$, and the vertex is at the point $(h, k)$. For the given equation $P(x) = 2(x - 8)^2 - 4$, $h = 8$ and $k = -4$, so the axis of symmetry is $x = 8$ and the vertex is $(8, -4)$.
