Answer:
(2, -1)
Explanation:
The given formula is y + 1 = -1/4 (x - 2)²
Vertex form of a parabola is y = a(x - h)² + k
To get the given formula in vertex form, subtract 1 from each side. The equation for the parabola becomes:
y = -1/4 (x - 2)² - 1
From this, we can take out (h, k), the vertex, and see that it is at (2, -1).
