Aparabola is given by the equation y = x2 + 4x + 4.
the vertex of the parabola is
. the focus of the parabola is
. the directrix of the parabola is given by the equation y =
.
note: separate coordinates inside parentheses with a comma.

Convert the equation into a standard form
y=x2+4x+4
y= (x+2)^2
From the equation
vertex is located at (-2,0)
Solve for a to get the coordinates of the focus, from the equation 
4a=1
a=1/4
Focus is located at (-2, 1/4)
The equation of the directrix
y=-1/4
