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.

the vertex of the parabola is:(-2,0)

the focus of the parabola is:(-2,)

the directrix of the parabola is:y=

Step-by-step explanation:

we know that for any general equation of the parabola of the type the vertex of the parabola is given by (h,k)

where and

therefore by the given data we have h=-2 and k=0

hence vertex=(-2,0)

the general equation of the parabola of the type ; the parabola symmetric around the y-axis has the focus from the centre i.e. the vertex (h,k) at a distance a as (h,k+a) and the directrix is given by y=k-a

so focus is

now the directrix of the parabola is .

no this is a nonlinear negative
