    Parabola Review

    • Parent Function: Represented by the equation y = x², serves as the simplest form of a parabola.

    • Vertex Form: Expressed as y = a(x-h)² + k, where (h, k) denotes the vertex of the parabola, and 'a' determines the parabola's width and direction.

    • Standard Form: Written as ax² + bx + c, this format highlights the coefficients which can aid in identifying the parabola's orientation and placement.

    • Axis of Symmetry: Calculated using x = -b/(2a), this line divides the parabola into two equal halves, crucial for determining vertex and graph shape.

    • Vertex AOS: The vertex of the parabola is found by plugging the axis of symmetry value back into the original equation. It indicates the highest or lowest point on the graph, depending on the direction of the parabola.

    • Domain: The domain of a parabola encompasses all real numbers, indicating that x can take any value.

    • Range: The range is determined by whether the parabola has a maximum or minimum point:

      • If minimum: (Y vertex, ∞)
      • If maximum: (-∞, y vertex)

    • Minimum: Occurs when the parabola opens upwards, indicating that the lowest point is at the vertex.

    • Maximum: Takes place when the parabola opens downwards, indicating that the highest point is at the vertex.
