Find the equation of the figure shown.

• (x-1)²/16 - (y+2)²/4 = 1

• (x+1)²/16 - (y-2)²/4 = 1

• (y+2)²/4 - (x-1)²/16 = 1

• (x-1)²/4 - (y+2)²/2 = 1

Center ?

• (-3 , 2)

• (2 , -3)

• (12 , 5)

• (5 , 12)

What is the directrix of the parabola, careful to put in proper form
(x - 4)² = 8(y + 3)

• y = - 3

• x= 5

• y= - 5

• y= 2

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)
