The focus is at (2,0) and the vertex is at (-4,0).  What is the equation of the parabola?

• y² = 24(x+4)
• (y+4)² = -12x
• x² = 16(y+4)
• (x+4)²  = -20y

Given this directrix and vertex, what would the equation of the parabola be?

• (y-2)² = 12(x-1)
• (y-2)² = 6(x-1)
• (x-1)² = 12(y-2)
• (x-1)² = 6(y-2)

What is the focus of the following parabola?
(y + 5)² = -12 (x - 2)

• (2, - 5)
• ( -5, 2)
• (1 , -5 )
• (-1, -5 )

What is the coordinate of the vertex?       (x+3)² = 4(y+5)  

• (3, 5) 
• (-3, -5) 
• (5, 3) 
• (-5,-3)

What is the coordinate of the focus?       (x+3)² = 4(y+5)  

• (-3, -4) 
• (-3, -6) 
• (-4, 5) 
• (-2, 5)
