This is a common question that we get from two audiences. It is most commonly asked by algebra students who want to calculate the point in the plane, when the equation of the parabola is given.... Question from Kenzie, a parent: The graph shows an arrow going upward crossing at the -2 on the x line and crossing the 3 on the x line and the vertex on the -6 on the y line. The answer is y=x^2 -x-6 I've tried 0 in place of x and y for -6 and -2 and 3 for x! Please help, Thanks: Hi Kenzie. It sounds like you are describing a parabola that opens upward, and indeed that is what the equation is

how to get the equation of a parabola

Derivation of the equation of a parabola Math Open Reference
If a≠0 , the equation y = ax 2 + bx + c is the standard form of a quadratic function and its graph is a parabola. If a > 0, the parabola opens upward and the lowest point (called the vertex) yields the minimum value of the function. how to find a health promotion job sa Question from Kenzie, a parent: The graph shows an arrow going upward crossing at the -2 on the x line and crossing the 3 on the x line and the vertex on the -6 on the y line.

How To Get The Equation Of A Parabola

State the vertex and focus of the parabola having the equation (y – 3) 2 = 8(x – 5). Comparing this equation with the conics form, and remembering that the h always goes with the x and the k always goes with the y , I can see that the center is at ( h , k ) = (5, 3) .

  • Equation of a parabola - derivation. Given a parabola with focal length f, we can derive the equation of the parabola. (see figure on right). We assume the origin (0,0) of the coordinate system is at the parabola's vertex.
  • If a≠0 , the equation y = ax 2 + bx + c is the standard form of a quadratic function and its graph is a parabola. If a > 0, the parabola opens upward and the lowest point (called the vertex) yields the minimum value of the function.
  • Comparing our equation to the form above we see that we must have \(h = - 3\) and \(k = - 8\) since that is the only way to get the correct signs in our function. Therefore, the vertex of this parabola is,
  • 12/03/2006 · Best Answer: Things you need to know Formula for a parabola (with vertical symmetry): (x-h)^2 = 4a(y-k) where "h" and "k" are the x and y corrdinates of the vertex, and "a" is the distance from the vertex to the focus.
