The vertex of a parabola is a point at which the parabola makes its sharpest turn. The vertex of f(x) = ax^2 + bx + c is given by (-b/2a, f(-b/2a)). Learn how to find vertex of a parabola from different forms like standard form, vertex form, and inter
Answer to: How do you find the vertex of the parabola y = 18(x - 5)^2 - 3? By signing up, you'll get thousands of step-by-step solutions to your...
What is the formula to find the axis of symmetry? The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form, y=ax2+bx+c , the axis of symmetry is a vertical line x=−b2a . What is the axis of symmetry ...
If you need to find the vertex of a parabola, however, the standard quadratic form is much less helpful. Instead, you'll want to convert your quadratic equation into vertex form. What Is Vertex Form? While the standard quadratic form is ax2+bx+c=y, the vertex form of a quadratic equat...

There are two different formulas that you can use to find the axis of symmetry. One formula works when the parabola's equation is invertex formand the other works when the parabola's equation is instandard form. Standard Form If your equation is inthe standard formy=ax2+bx+cy=ax2+bx+...
A parabola is a conic section, or a graph in the shape of a U that opens either upward or downward. A parabola opens from the vertex, which is the lowest point on a parabola that opens up, or the lowest point on one that opens down -- and is symmetrical.
