Discover how to accurately determine the vertex of a parabola from quadratic equations in standard form (y = ax² + bx + c). Our free Vertex Calculator simplifies complex algebra, providing precise coordinates and the axis of symmetry instantly. Understand the key features of any quadratic function with ease.
Formula:
For a quadratic equation in standard form y = ax² + bx + c, the vertex (h, k) is calculated as:
h = -b / (2a)
k = f(h) = a(h)² + b(h) + c
Where a, b, and c are coefficients from your quadratic equation.
