Assuming the missing symbol there is an equals sign, then we have:
y - 2x2 - 4x = 4
We can find it's vertex very easily by solving for y, and finding where it's derivative equals zero:
y = 2x2 + 4x + 4
y' = 4x + 4
0 = 4x + 4
x = -1
So the vertex occurs Where x = -1. Now we can plug that back into the original equation to find y:
y = 2x2 + 4x + 4
y = 2 - 4 + 4
y = 2
So the vertex is at the point (-1, 2)

How do you graph parabola given its vertex?
The vertex of a parabola doe not provide enough information to graph anything - other than the vertex!
What is the relationship of a vertex to a parabola?
The vertex is either the minimum (very bottom) or maximum (very top) of a parabola.

What is the vertex of the parabola y equals x2 plus 8x plus 5?
The vertex has a minimum value of (-4, -11)
What is the equation of a parabola with a vertex at 0 0 and a focus at 0 6?
The standard equation for a Parabola with is vertex at the origin (0,0) is, x2 = 4cy if the parabola opens vertically upwards/downwards, or y2 = 4cx when the parabola opens sideways. As the focus is at (0,6) then the focus is vertically above the vertex and we have an upward opening parabola. Note that c is the distance from the vertex to the focus and in this case has a value of 6 (a positive number). The equation is thus, x2 = 4*6y = 24y
