1. find the standard form of the equation of the parabola with a focus at (0, -9) and a directrix y = 9.
a ) y = negative one divided by ninex2
b ) y2 = -36x
c ) y = negative one divided by thirty sixx2
d ) y2 = -9x
2. find the standard form of the equation of the parabola with a vertex at the origin and a focus at (0, 9).
a ) y = one divided by thirty sixx2
b ) y = one divided by ninex2
c ) y2 = 9x
d ) y2 = 36x
3. find the vertex, focus, directrix, and focal width of the parabola.
x = 4y2
vertex: (0, 0); focus: one divided by four comma zero; directrix: x = negative one divided by four; focal width: 0.25
vertex: (0, 0); focus: one divided by sixteen comma zero; directrix: x = one divided by sixteen; focal width: 16
vertex: (0, 0); focus: zero comma one divided by sixteen; directrix: y = negative one divided by sixteen; focal width: 16
vertex: (0, 0); focus: one divided by sixteen comma zero; directrix: x = negative one divided by sixteen; focal width: 0.25
4. find the standard form of the equation of the parabola with a focus at (3, 0) and a directrix at x = -3.
a ) y = one divided by twelvex2
b ) -12y = x2
c ) x = one divided by twelvey2
d ) y2 = 6x
