Hi,

parabola: Vertex V(-1, 0), focus F(-4, 0)  p = -3

 y^2 = -12(x + 1)

the vertex form of a Parabola opening right(a>0) or left(a<0), x=a%28y-k%29%5E2+%2Bh

 where(h,k) is the vertex and  y = k  is the Line of Symmetry

The standard form is %28y+-k%29%5E2+=+4p%28x+-h%29, where  the focus is (h +p,k )
