Given: The equation of a parabola below

To Determine: The vertex, focus, and directrix of the parabola
Let us re-write the given equation

The general equation of the parabola with vertex (h, k) is of this form


Let us compare the general equation with the given equation

Therefore




Hence,
Vertex = (1, -4)
Focus = (1, -1)
Directrix, y = -7
