How to identify vertex, focus and directrix for a parabola conic sections

The video tutorial covers the identification and analysis of conic sections, specifically focusing on parabolas. The teacher explains how to rewrite equations to identify the vertex, focus, and directrix. The tutorial includes calculations for determining the direction of the parabola and understanding the axis of symmetry. The session concludes with a Q&A segment to address student queries.

What is the first step in identifying a conic section from an equation?

• Determining the axis of symmetry

• Calculating the vertex

• Rewriting the equation to match a standard form

• Finding the value of P

How do you calculate the value of P in a conic section equation?

• By subtracting 4 from both sides

• By multiplying the coefficient of X by 4

• By dividing the coefficient of Y by 4

• By adding 4 to both sides

What does the value of P indicate in the context of a parabola?

• The height of the parabola

• The angle of the parabola

• The distance from the vertex to the focus

• The width of the parabola

Which coordinate do the vertex and focus share in a parabola?

• The origin

• The Z coordinate

• The Y coordinate

• The X coordinate

How is the directrix of a parabola related to the axis of symmetry?

• It is opposite to the axis of symmetry

• It is the same as the axis of symmetry

• It is perpendicular to the axis of symmetry

• It is parallel to the axis of symmetry
