Answer:
Explanation:
Vertex form of quadratic function:
Given a graph with:
- Vertex = (-2, 6)
- Points: (-6, -6), (2, -6)
We can see that:
- h = -2 and k = 6, a is negative (parabola opens down)
The equation becomes:
Substitute coordinates (-6, -6) into the equation to find the value of a:
- -6 = a(-6 + 2)² + 6
- -6 = 16a + 6
- 16a = -12
- a = -12/16
- a = -3/4
The function becomes:
