Question

Find the vertex, focus, directrix, and focal width of the parabola.
-1/12 x^2=y

Vertex: (0, 0); Focus: (0, -3); Directrix: y = 3; Focal width: 48

Vertex: (0, 0); Focus: (-6, 0); Directrix: x = 3; Focal width: 48

Vertex: (0, 0); Focus: (0, 3); Directrix: y = -3; Focal width: 3

Vertex: (0, 0); Focus: (0, -3); Directrix: y = 3; Focal width: 12
