**Writing Quadratic Equations & Functions In Vertex**

If the vertex and another point on the parabola is known, it is easy to determine the equation of the parabola: Substitute the coordinates of the vertex into h and k , and substitute in the coordinates of the other point for x and y , and then solve for a , remembering to use Order of Operations (BEDMAS).... After yesterday's lesson, my students have the Standard Equation for a Parabola on their conics reference sheet. Today's Bell work requires students to think about the information they need to acquire to determine the equation in standard form for a parabola whose vertex and focus are known.

When written in "vertex form": â€¢ (h, k) is the vertex of the parabola, and x = h is the axis of symmetry. â€¢ the h represents a horizontal shift (how far left, or right, the graph has shifted from x = 0).... When written in "vertex form": â€¢ (h, k) is the vertex of the parabola, and x = h is the axis of symmetry. â€¢ the h represents a horizontal shift (how far left, or right, the graph has shifted from x = 0).

## How To Write Parabola Equations In Vertex Form

### In vertex form, a quadratic function is written as y = a(x-h) 2 + k See also Quadratic Explorer - standard form. In the applet below, move the sliders on the right to change the values of a, h and k and note the effects it has on the graph.

- The vertex form of a parabola's equation is generally expressed as : $$ y= a(x-h)^ 2 + k $$ (h,k) is the vertex If a is positive then the parabola opens upwards like a regular "U".
- Vertex form of a parabola gives the equation of the parabola in terms of vertex coordinates(h,k). If we identify the vertex of a quadratic, we can just plug it in the formula and get the equation. If we identify the vertex of a quadratic, we can just plug it in the formula and get the equation.
- We can see more clearly here by one, or both, of the following means: 1. determining the vertex using the formula for the coordinates of the vertex of a parabola, or 2. completing the square and placing the equation in vertex form. The latter encompasses the former and allows us to see the transformations that yielded this graph. Doing so yields the following two equivalent equations
- When written in "vertex form": â€¢ (h, k) is the vertex of the parabola, and x = h is the axis of symmetry. â€¢ the h represents a horizontal shift (how far left, or right, the graph has shifted from x = 0).
