Parabola Vertex Calculator

About the Parabola Vertex Calculator

This calculator quickly computes the vertex coordinates of a quadratic function y = ax² + bx + c, with results rounded to 4 decimal places. Main features include:

• Vertex calculation: accurately computes the vertex coordinates (h, k) of the parabola.
• Full formula support: accepts all coefficients of the standard quadratic function.
• Input validation: automatically detects invalid input and shows a prompt (e.g., it is not a quadratic function when a = 0).
