Learn how to write the equation of a parabola

The video tutorial guides students on how to graph and write equations by understanding key components such as the vertex, focus, and directrix. It emphasizes the importance of identifying these elements and using them to determine the equation. The tutorial provides a step-by-step approach to calculating the value of P and finalizing the equation format, encouraging students to focus on understanding rather than memorization.

What should you always remember to graph when working with parabolas?

• Only the vertex

• The vertex, focus, and directrix

• Just the focus

• The directrix only

In the given example, where is the vertex located?

• (0,4)

• (4,0)

• (4,4)

• (0,0)

What is the value of P in the example provided?

• 5

• 4

• 3

• 2

Which variable is squared in the equation of the parabola?

• Both X and Y

• X

• Neither

• Y

What is the final form of the parabola equation given in the example?

• Y^2 = 4(x - H)

• X^2 = 4(y - K)

• Y^2 = 4P(x - H)

• X^2 = 4P(y - K)
