Writing the Equation of a Parabola

Vertex: (2, 3) Focus: (2, 5)

y=1/8(x-2)²+3

Vertex: (-1, -2) Focus: (5, -2)

x=-1/16(y+2)²-1

Vertex: (2, -2) Directrix: x=-3

x=1/20(y+2)²+2

Vertex: (1, 3) Directrix: y=4

y=-1/4(x-1)²+3

Focus: (0, 3) Directrix: y=-3

y=1/12x²

Focus: (-3, 2) Directrix: x=3

x=-1/12(y-2)²
