The triangles ABC and A'B'C' are shown in the diagram below. The transformation is a reflection in the line 
. This is proved by the fact that the distance between each corner ABC to the mirror line equals to the distance between the mirror line to A'B'C'.
Answer:
Step-by-step explanation:
we know that
The standard equation of a horizontal parabola is equal to
where
(h,k) is the vertex
(h+p,k) is the focus
In this problem we have
(h,k)=(0,0) ----> vertex at origin
(h+p,k)=(-4,0)
so
h+p=-4
p=-4
substitute the values
