Question 179

Multiple Choice

Find an equation for the parabola described.
-Vertex at (7,−9) ;( 7 , - 9 ) ; focus at (3,−9) ( 3 , - 9 )


A) (x+8) 2=−4(y−4) ( x + 8 ) ^ { 2 } = - 4 ( y - 4 )
B) (x+8) 2=4(y−4) ( x + 8 ) ^ { 2 } = 4 ( y - 4 )
C) (y+4) 2=−12(x−8) ( y + 4 ) ^ { 2 } = - 12 ( x - 8 )
D) (y+9) 2=16(x−7) ( y + 9 ) ^ { 2 } = 16 ( x - 7 )
