Locus Vertex Focus

a pair of special points used in describing conic sections. A circle and a parabola have one focus; an ellipse and a hyperbola have two foci.

• Foci

• Directrix

• Eccentricity

• Vertex of a conic section

the locus of all points in the plane such that the absolute value of the difference of the distances from two given points in the plane, called foci, is constant

• Circle

• Ellipse

• Parabola

• Hyperbola

What is the equation of a parabola with vertex (3, 4) and focus (7, 4)?

• 16(x - 3) = (y - 4)²

• 28(x - 3) = (y - 4)²

• -28(x - 3) = (y - 4)²

• -16(x - 3) = (y - 4)²

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)

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

A hyperbola has vertices (±5, 0) and one focus at (6, 0). What is the equation of the hyperbola in standard form?

• x²/25 + y²/11 = 1

• x²/5 - y²/11 = 1

• x²/11- y²/25 = 1

• x²/25 - y²/11= 1

Find the equation of the parabola with vertex (5,1) and Focus (2,1).

• Vertical Hyperbola
• Vertical Ellipse
• Horizontal Hyperbola
• Horizontal Ellipse
