Answer:
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 .
