Find the vertex, focus, directrix, and focal width of the parabola. x = 10y2
Vertex: (0, 0); Focus: one divided by forty comma zero; Directrix: x = negative one divided by forty; Focal width: 0.1
Vertex: (0, 0); Focus: one divided by ten comma zero; Directrix: x = negative one divided by ten; Focal width: 0.1
Vertex: (0, 0); Focus: one divided by forty comma zero; Directrix: x = one divided by forty; Focal width: 40
Vertex: (0, 0); Focus: zero comma one divided by forty; Directrix: y = negative one divided by forty; Focal width: 40
