Question 124

Multiple Choice

Write an equation for the parabola.
-vertex: (4,−2) ( 4 , - 2 ) , directrix: x=9x = 9


A) x2=−20(y−4) x ^ { 2 } = - 20 ( y - 4 )
B) (x+2) 2=−20(y−4) ( x + 2 ) ^ { 2 } = - 20 ( y - 4 )
C) (y−4) 2=−20(x+2) ( y - 4 ) ^ { 2 } = - 20 ( x + 2 )
D) (y+2) 2=−20(x−4) ( y + 2 ) ^ { 2 } = - 20 ( x - 4 )
