Question

Choose the correct option for the graph, focus, and directrix of the parabola.
y² = -8x

Accepted Answer

Directrix: x = 2; Focus: (-2, 0)

Graph of the parabola y² = -8x with focus at (-2,0) and directrix x=2.

Answer

Directrix: x = -2; Focus: (2, 0)

Graph of the parabola y² = -8x with focus at (2,0) and directrix x=-2.

Answer

Directrix: y = -2; Focus: (0, 2)

Graph of the parabola y² = -8x with focus at (0,2) and directrix y=-2.

Answer

Directrix: y = 2; Focus: (0, -2)

Graph of the parabola y² = -8x with focus at (0,-2) and directrix y=2.
