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
Explanation:
Step 1: Define
y = -3(x + a)² - 6
↓ Identify variables
a = -3
b = 1
(h, k) = (-a, -6)
