-$$( y + 3 ) ^ { 2 } = 8 ( x + 4 )$$
A) $( - 6 , - 3 ) , x = - 2 , y = - 3$
B) $( - 1 , - 4 ) , x = - 5 , y = - 4$
C) $( - 2 , - 3 ) , x = - 6 , y = - 3$
D) $( 6,3 ) , x = 2 , y = 3$

Quizplus · Accepted Answer

The vertex is (-4, -3). The axis of symmetry is x = -4. The focus is (-6, -3) and the directrix is x = -2.

Give the Focus, Directrix, and Axis for the Parabola (y+3)2=8(x+4)( y + 3 ) ^ { 2 } = 8 ( x + 4 )(y+3)2=8(x+4)

Give the Focus, Directrix, and Axis for the Parabola $( y + 3 ) ^ { 2 } = 8 ( x + 4 )$
