Find the vertex, focus, directrix, and focal width of the parabola.
x2 = 28y
Vertex: (0, 0); Focus: (0, -7); Directrix: x = -7; Focal width: 112
Vertex: (0, 0); Focus: (7, 0); Directrix: x = 7; Focal width: 7
Vertex: (0, 0); Focus: (0, 7); Directrix: y = -7; Focal width: 28
Vertex: (0, 0); Focus: (7, 0); Directrix: y = 7; Focal width: 112
