A
Given a quadratic in standard form : y = ax² + bx + c ( a ≠ 0 ), then
The x-coordinate of the vertex is
= - 
y = - 3x² + 2x - 7 is in standard form
with a = - 3, b = 2 and c = - 7, hence
= - 
= 
Substitute this value into the equation for y-coordinate
y = - 3 ()² + 2 ( ) - 7
= - + 
- 
= - 
vertex = ( , - ) → A
