Conic Sections Parabola

What is the p-value of this parabola?

• 4

• -8

• 2

• 8

"A set of points in a plane that are equidistant from

a fixed point and a fixed line" is

• Directrix

• Prabola

• Focus

• Parameter

In parabola definition " the fixed point" is called :

• Directrix

• Eccentricity

• Focus

• Parabola

In parabola definition " the fixed line" is called :

• Directrix

• Eccentricity

• Focus

• Parabola

The focus of a parabola is F(-2, 0) and its vertex is at

the origin. Find the equation of the directrix.

• x=2

• x=-2

• x=4

• x=5

The focus of a parabola is F(3, 0) and its vertex is at

the origin. Find the equation of the directrix.

• x=3

• x=-3

• x=0

• x=1

The focus of a parabola is F(0, -5) and its vertex is at

the origin. Find the equation of the directrix.

• y=5

• y=-5

• y=7

• y=4

If the directrix is y = 4 and the focus is at

(0, -4), the value of parameter is:

• 8

• -8

• 2

• -2

Eccentricity of parabola is always

• 2

• 1

• 5

• 7

The length of the line segment between the focus and the directrix of a parabola is called:

• Parabola

• Directrix

• Parameter

• Focus
