How to find a parabola’s equation using its Vertex Form
- Step 1: use the (known) coordinates of the vertex, (h,k), to write the parabola’s equation in the form: y=a(x−h)2+k.
- Step 2: find the value of the coefficient a by substituting the coordinates of point P into the equation written in step 1 and solving for a.
What is an example of a parabola equation?
Parabola Examples Example 1: The equation of a parabola is y2 = 24x. Find the length of the latus rectum, focus, and vertex. Example 2: The equation of a parabola is 2(y-3)2 + 24 = x.
What is the formula for the equation of a parabola?
The equation of a parabola can be written in two basic forms: Form 1: y = a( x – h) 2 + k. Form 2: x = a( y – k) 2 + h.
How do you solve quadratic equations with parabolas?
Given y = ax2 + bx + c , we have to go through the following steps to find the points and shape of any parabola:
- Label a, b, and c.
- Decide the direction of the paraola:
- Find the x-intercepts:
- Find the y-intercept:
- Find the vertex (h,k):
- Plot the points and graph the parabola.
How do you write an equation of a parabola in standard form?
For parabolas that open either up or down, the standard form equation is (x – h)^2 = 4p(y – k). For parabolas that open sideways, the standard form equation is (y – k)^2 = 4p(x – h). The vertex or tip of our parabola is given by the point (h, k).
What is parabola and examples?
A parabola is nothing but a U-shaped plane curve. Any point on the parabola is equidistant from a fixed point called the focus and a fixed straight line known as the directrix. Terms related to Parabola.
What are examples of quadratic equations?
Examples of quadratic equations in other forms include:
- x(x – 2) = 4 [upon multiplying and moving the 4, becomes x² – 2x – 4 = 0]
- x(2x + 3) = 12 [upon multiplying and moving the 12, becomes 2x² – 3x – 12 = 0]
- 3x(x + 8) = -2 [upon multiplying and moving the -2, becomes 3x² + 24x + 2 = 0]
