Final answer:
The standard form of a parabola is given by the equation y = ax² + bx + c. The vertex form of a parabola is y = a(x - h)² + k. The factored form of a parabola is y = a(x - r)(x - s).
Step-by-step explanation:
The standard form of a parabola is given by the equation y = ax² + bx + c, where a, b, and c are constants.
Option A) Vertex form: The vertex form of a parabola is y = a(x - h)² + k, where (h, k) is the vertex of the parabola.
Option B) Factored form: The factored form of a parabola is y = a(x - r)(x - s), where r and s are the x-intercepts of the parabola.
