Parabola

What is the directrix of the parabola
(x - 4)² = 8(y + 3)?

• y = - 3

• x= 5

• y= - 5

• y= 2

Given the equation of the parabola, where would the VERTEX be? (put in standard form)

• ( 3 , 3)

• (24, 3)

• ( - 24, 3)

• (-3, 3)

Identify the conic from the equation: y² -4x -2y -2 = 0

• circle

• ellipse

• parabola

• hyperbola

Find the equation of the parabola with vertex (4,6) and focus (4,9).

• (x-4)² = 12(y - 6)

• (x-4)² = 3(y - 6)

• (y-6)² = 3(x-4)

• (y-6)² = 12(x-4)

Write the equation for the parabola.

• (y-2)² = -4(x-3)

• (y-2)² = -16(x-3)

• (x-3)² = -4(y-2)

• (x-3)² = -16(y-2)

Convert the equation x² + 4y² + 2x + 24y + 21 = 0 into standard form.

Identify the focus and directrix of the parabola: (y-2)² = 24(x-5)

• focus: (5, 7); directrix: y = -4

• focus: (5, -4); directrix: y = 7

• focus: (11, 2); directrix: y = -1

• focus: (-1, 2); directrix: y = 11
