Graph the parabola by identifying the focus and vertex

What is the significance of the vertex in graphing a parabola?

• It is the point where the parabola intersects the y-axis.

• It defines the slope of the parabola.

• It is the highest or lowest point of the parabola.

• It determines the width of the parabola.

How does the value of P affect the orientation of a parabola?

• It determines the color of the graph.

• It affects whether the parabola opens up or down.

• It changes the shape of the parabola to a circle.

• It decides whether the parabola opens left or right.

What is the role of the focus in a parabola?

• It is a point that helps in defining the parabola's shape.

• It is the midpoint of the parabola.

• It is a point that lies on the directrix.

• It is the endpoint of the parabola.

How is the directrix of a parabola defined?

• As a line parallel to the axis of symmetry.

• As a point on the parabola.

• As a line perpendicular to the axis of symmetry.

• As a curve that intersects the parabola.

What is the relationship between the vertex and the directrix?

• The directrix is equidistant from the vertex as the focus but in the opposite direction.

• The directrix is always above the vertex.

• The directrix is the same as the vertex.

• The directrix is always below the vertex.
