Find the Vertex, Focus, and Directrix of the Parabola with the Given

Question 177

Multiple Choice

Find the vertex, focus, and directrix of the parabola with the given equation.
- (x2) 2=20(y3) ( x - 2 ) ^ { 2 } = - 20 ( y - 3 )


A) vertex: (2,3) ( 2,3 )
focus: (2,2) ( 2 , - 2 )
 directrix: y=8\text { directrix: } y=8

B) vertex: (2,3) ( - 2 , - 3 )
focus: (2,8) ( - 2 , - 8 )
 directrix: y=2\text { directrix: } y=2

C) vertex: (2,3) ( 2,3 )
focus: (2,8) ( 2,8 )
 directrix: x=2\text { directrix: } x=-2

D) vertex: (3,2) ( 3,2 )
focus: (3,3) ( 3 , - 3 )
 directrix: y=7\text { directrix: } y=7




directrix: y=8y = 8 \quad directrix: y=2y = 2 \quad directrix: x=2x = - 2 \quad directrix: y=7y = 7
