Find the vertex, focus, and directrix of the parabola: x² = 32y

• Vertex: (0, 0) Focus: (0,8) Directrix: y= -8

• Vertex: (0, 0) Focus: (8,0) Directrix: y= 8

• Vertex: (0, 0) Focus: (0,-8) Directrix: x= -8

• Vertex: (0, 0) Focus: (8, 0) Directrix: x= 8

Find the vertex, focus, and directrix of the parabola: -(1/20)x² = y

• Vertex: (0, 0) Focus: (-10,0) Directrix: x = 5

• Vertex: (0, 0) Focus: (0,5) Directrix: y=5

• Vertex: (0, 0) Focus: (0,5) Directrix: y=-5

• Vertex: (0, 0) Focus: (0, -5) Directrix: y = 5

Find the directrix $y=\frac{1}{16}x^2$ 

• y = 4

• x= 1

• y= -4

• y= 1

If a parabola has a focus at (6,0) and a vertex at the origin...what is the equation of the directrix?

• y= 6

• y= -6

• x= 6

• x= -6

What is the equation of a parabola with

Focus (-1,2) and the directrix y = 3 ?

•  $y=\frac{1}{2}\left(x+1\right)^2+2$ 

•  $y=-\frac{1}{2}\left(x+1\right)^2+\frac{5}{2}$  

•  $y=-5\left(x+1\right)^2-2$  

•  $x=-\frac{1}{2}\left(y+1\right)^2+\frac{5}{2}$
