Vertex = $(-3, 2)$

The vertex is identified from this formula.

$a(x - x_1)^2$ = $(y - y_1)$

Whatever what x_1 equals to is the $x$ -coordinate of the vertex. Whatever what $y_1$ is the $y$ -coordinate of the vertex.

In our case,

$x_1$ = -3 and $y_1$ = 2

How do you identify the vertex for ( x + 3) ^ { 2} = - 8( y - 2)( x + 3) ^ { 2} = - 8( y - 2)?
