Identify the vertex, focus and directrix of a parabola

The video tutorial explains how to graph a parabola by identifying the vertex, calculating the P value, and determining the direction of the graph. It covers the relationship between the vertex, focus, and directrix, and how these elements affect the orientation of the parabola. The tutorial emphasizes the importance of understanding the signs of P and how they influence whether the parabola opens upwards or downwards.

What is the vertex of the parabola discussed in the video?

• (2, -2)

• (0, 0)

• (-2, 2)

• (2, 2)

How is the value of P calculated in the video?

• P = 16 / 4

• P = 16 / 2

• P = 8 / 4

• P = 4 / 4

If P is positive, in which direction does the parabola open?

• Upwards

• Downwards

• Left

• Right

Where is the focus of the parabola located?

• (2, 2)

• (2, -2)

• (0, 0)

• (-2, 2)

What is the equation of the directrix for the parabola?

• Y = 6

• X = 6

• Y = -6

• X = -6
