    Answer:

    Vertex is (-a, -6), where a ≠ 0.

    General Formulas and Concepts:

    Algebra I

    • Coordinates (x, y)
    • Quadratics

    Algebra II

    Vertex Form: y = a(bx – h)² + k

    • a is the vertical scale factor
    • b is the horizontal scale factor
    • (h, k) is the vertex

    Step-by-step explanation:

    Step 1: Define

    y = -3(x + a)² – 6

    ↓ Identify variables

    a = -3

    b = 1

    (h, k) = (-a, -6)
