1. Vertex: (2, -4)
Axis of Symmetry: x = 2
Domain: All real numbers
Range: y ≥ -4
Increasing: x > 2
Decreasing: x < 2
Roots/Zeros: x = 0, x = 4
y-intercept: (0, 0)
Minimum/Maximum: Minimum at (2, -4)

2. Vertex: (-1, 3)
Axis of Symmetry: x = -1
Domain: All real numbers
Range: y ≤ 3
Increasing: x < -1
Decreasing: x > -1
Roots/Zeros: x = -3, x = 1
y-intercept: (0, 2)
Minimum/Maximum: Maximum at (-1, 3)

3. Vertex: (1, -2)
Axis of Symmetry: x = 1
