A. vertex: (3, 6)
focus: (3, 6.25)
directrix: y = 5.75
What are the vertex, focus, and directrix of the parabola with equation y = x2 – 6x + 15?
A. vertex: (3, 6)
focus: (3, 6.25)
directrix: y = 5.75
B. vertex: (6, 3)
focus: (6, 3.25)
directrix: x = 2.75
C. vertex: (3, −6)
focus: (3, −5.75)
directrix: y = −6.25
D. vertex: (3, −6)
focus: (3.25, −6)
directrix: y = 2.75
