How to find the focus and directrix of a parabola with the vertex not at the center with

The video tutorial explains how to identify which variable is squared in a graph, find the vertex, calculate the focus, and determine the directrix of a parabola. It emphasizes the importance of labeling to avoid confusion between the vertex and focus. The tutorial also covers how to graph the parabola, ensuring it opens towards the focus.

What is the first step in determining the direction a parabola opens?

• Identifying the squared variable

• Determining the directrix

• Calculating the focus

• Finding the vertex

Why is it important to label the vertex when graphing a parabola?

• To ensure the graph opens in the correct direction

• To calculate the value of P accurately

• To avoid mixing it up with the directrix

• To prevent confusion with the focus

How does the formula X + 2 affect the graph of a parabola?

• It shifts the graph 2 units down

• It shifts the graph 2 units to the left

• It shifts the graph 2 units to the right

• It shifts the graph 2 units up

What is the value of P if 4P equals 2?

• 1

• 1/2

• 1/4

• 2

In which direction does a parabola open relative to its focus?

• Parallel to the directrix

• Towards the focus

• Towards the directrix

• Away from the focus
