(1 point)
Responses
vertex (–3, –3); focus (0, 3); directrix y = 3
vertex (–3, –3); focus (0, 3); directrix y = 3
vertex (3, 3); focus (3, 6); directrix y = 0
vertex (3, 3); focus (3, 6); directrix y = 0
vertex (3, –3); focus (0, 6); directrix y = –3
vertex (3, –3); focus (0, 6); directrix y = –3
vertex (–3, 3); focus (3, –3); directrix y = 0
The correct answer is:
vertex (3, -3); focus (3, 0); directrix y = -6
