- The parabola equation in its vertex form is y = a(x - h)² + k, where: a — Same as the a coefficient in the standard form; h — x-coordinate of the parabola vertex; and k — y-coordinate of the parabola vertex.

The standard equation of a parabola is used to represent a parabola algebraically in the coordinate plane. The general equation of a parabola can be given as, y = a(x-h) 2 + k or x = a(y-k) 2 +h, where (h,k) denotes the vertex.
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.
Mar 12, 2024 · Find the coordinates of the focus of the parabola. The x-coordinate of the focus is the same as the vertex's (x₀ = -0.75), and the y-coordinate is: y₀ = c - (b² - 1)/(4a) = -4 - (9-1)/8 = -5
The general form of a parabola's equation is converted into the vertex form by completing the square — or by using the following formula to get the value of h, being the x-coordinate of the vertex: h = − b /(2 a )
2 days ago · To graph a parabola, we find the vertex of the parabola and the axis of symmetry, and then, sketch the curve. For the equation of the parabola y = ax 2 + bx + c, the x-coordinate for the vertex is ${h=-\dfrac{b}{2a}}$
Step A: Use the formula x=-b/2a to find the x-coordinate value of the vertex point. Step B: Input the x-coordinate value from Step A into the function to find the y-coordinate value. The key concepts of what is the vertex of a parabola and how to find the vertex of a parabola is shown in Figure 02 below. Figure 02: What is the vertex of a parabola?
In mathematics, a parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped. It fits several superficially different mathematical descriptions, which can all be proved to define exactly the same curves. One description of a parabola involves a point (the focus) and a line (the directrix).
