axis of symmetry: x = 2
x-intercepts: 1 and 3; y-intercept: -3
domain: (-?, ?); range: (-?, 1]
B. vertex: (-2, 1)
axis of symmetry: x = -2
x-intercepts: -1 and - 3; y-intercept: -3
domain: (-?, ?); range: (-?, 1]
C. vertex: (2, -1)
axis of symmetry: x = 2
x-intercepts: 1 and 3; y-intercept: 3
domain: (-?, ?); range: [-1, ?)
D. vertex: (-2, -1)
axis of symmetry: x = -2
