To find the vertex form of the graphed equation, we need to determine the vertex coordinates.
From the given points, we can see that the vertex is at (4, 8).
Therefore, the vertex form of the graphed equation is:
y = a(x - h)^2 + k
Substituting the vertex coordinates, the equation becomes:
y = 2 * (x - 4)^2 + 8
