1) the parabola opens down

2) the focal diameter equals -2

3) the directrix lies on the line y=2

2016-02-01 17:12:17 UTC

x-1 = (y+2)^2 /2

1) Vertex = (1,-2)

2) Focus = (0, 1/2)

3) Directrix: x= 1/2

1. Equation: y^2= -12x

2. Opens downward

3. vertex: (0,0)

y = -12(x^2)

1. Opens down

2. p = -3

3. Focus at (0,-12)

2016-02-01 17:14:40 UTC

1. The equation is x^2=20y

2. The focal diameter is 20

3. The vertex is (0,0)

2016-02-01 17:18:00 UTC

1. focus=(0,-13/4)

2. vertex= (0,-3)

3. axis of symmetry: x=0
