What is the general form of a quadratic equation?

Back

The general form is y = ax² + bx + c, where a, b, and c are constants and a ≠ 0.

What is the vertex of a parabola?

Back

The vertex is the highest or lowest point of the parabola, depending on its orientation.

What is the significance of the vertex form of a quadratic equation?

Back

The vertex form is y = a(x-h)² + k, where (h, k) is the vertex, making it easy to graph.
