A) $\quad ( 0,2 )$
B) $\quad ( 2 , - 5 )$
C) $\quad ( - 5,2 )$
D) $\quad ( - 5,0 )$
E) $\quad ( 0 , - 5 )$

The vertex form of a parabola is $y = a(x - h)^2 + k$, where $(h, k)$ is the vertex. For the given equation $y = 2x^2 - 5$, it is already in a form where $h = 0$ and $k = -5$, making the vertex $(0, -5)$.
