How to find vertex, focus, directrix of a parabola
This high or low point is called the vertex of the graph. The parabola is symmetric about a vertical line, called the axis of symmetry, that runs through the vertex. The y y -intercept is the point where the parabola intersects the y y -axis. The graph of a quadratic function always has exactly one y y - intercept.

The vertex always falls halfway between the focus and directrix. The key pieces of information in determining the equation of a parabola are: 1) the vertex: this gives us the values for \(h\) and \(k\) for the equation. 2) the orientation: this allows us to determine the appropriate form of the equation a) \(\quad(x-h)^{2}=4 p(y-k)\)

Standard form: y = ax 2 + bx + c Vertex Form: y = a (x - h) 2 + k Intercept Form: y = a (x - p) (x - q) In each of the cases, the parabola opens up if a > 0, and it opens down if a < 0. These types of parabolas are quadratic functions. Left/Right Opened Parabolas:

Finding the vertex of the quadratic by using the equation x=-b/2a, and then substituting that answer for y in the orginal equation. Then, substitute the vertex into the vertex form equation, y=a (x-h)^2+k. (a will stay the same, h is x, and k is y). Also, remember that your h, when plugged into the equation, must be the additive inverse of what.

A parabola is defined as 𝑦 = 𝑎𝑥² + 𝑏𝑥 + 𝑐 for 𝑎 ≠ 0 By factoring out 𝑎 and completing the square, we get 𝑦 = 𝑎 (𝑥² + (𝑏 ∕ 𝑎)𝑥) + 𝑐 = = 𝑎 (𝑥 + 𝑏 ∕ (2𝑎))² + 𝑐 − 𝑏² ∕ (4𝑎) With ℎ = −𝑏 ∕ (2𝑎) and 𝑘 = 𝑐 − 𝑏² ∕ (4𝑎) we get 𝑦 = 𝑎 (𝑥 − ℎ)² + 𝑘 (𝑥 − ℎ)² ≥ 0 for all 𝑥 So the parabola will have a vertex when (𝑥 − ℎ)² = 0 ⇔ 𝑥 = ℎ ⇒ 𝑦 = 𝑘

The x-coordinate of the vertex can be found by the formula −b 2a − b 2 a, and to get the y value of the vertex, just substitute −b 2a − b 2 a, into the the equqation as shown in the diagram and example below: Finding Vertex from Vertex Form It's called 'vertex form' for a reason! The vertex is just (h, k) from the equation. Related Links:

The standard equation of a parabola is. y = ax2 + bx + c y = a x 2 + b x + c . But the equation for a parabola can also be written in "vertex form": y = a(x − h)2 + k y = a ( x − h) 2 + k. In this equation, the vertex of the parabola is the point (h, k) ( h, k) . You can see how this relates to the standard equation by multiplying it out:

Vertex of a Parabola Formula. The point where the parabola and its axis of symmetry intersect is called the vertex of a parabola. It is used to determine the coordinates of the point on the parabola's axis of symmetry where it crosses it. For standard equation of a parabola y = ax 2 + bx + c, the vertex point is the coordinate (h, k).
