axis of symmetry: x = 3
x-intercepts: 1 and 5; y-intercept: -5
domain: (-?, ?); range: (-?, 4]

B. vertex: (-3, 4)
axis of symmetry: x = -3
x-intercepts: -1 and - 5; y-intercept: -5
domain: (-?, ?); range: (-?, 4]

C. vertex: (-3, -4)
axis of symmetry: x = -3
x-intercepts: -1 and - 5; y-intercept: 5
domain: (-?, ?); range: [-4, ?]
