8y = -(x^2 + 6x - 7) = -(x^2 + 6x + 9) + 16
y = -1/8 (x + 3)^2 + 2 ... vertex form
-1/8 ... opens downward
vertex is (-3,2)
... midway between focus and directrix
focus is (-3,0)
axis of sym ... x = -3
directrix is ... y = 4
y = -1/8 (x + 3)^2 + 2 ... vertex form
-1/8 ... opens downward
vertex is (-3,2)
... midway between focus and directrix
focus is (-3,0)
axis of sym ... x = -3
directrix is ... y = 4
