Find the vertex, focus, directrix, and focal width of the parabola.
negative 1 divided by 20 times x squared = y
Vertex: (0, 0); Focus: (-10, 0); Directrix: x = 5; Focal width: 80
Vertex: (0, 0); Focus: (0, -5); Directrix: y = 5; Focal width: 20
Vertex: (0, 0); Focus: (0, -5); Directrix: y = 5; Focal width: 80
Vertex: (0, 0); Focus: (0, 5); Directrix: y = -5; Focal width: 5
