axis of symmetry: x = -9
x-intercepts: 2 and - 4
y-intercept: -8
domain: (-?, ?)
range: (-9, ?)
C. vertex: (-1, -9)
axis of symmetry: x = -1
x-intercepts: 2 and - 4
y-intercept: -8
domain: [-9, ?)
range: (-?, ?)
D. vertex: (-1, -9)
axis of symmetry: x = -1
x-intercepts: 2 and - 4
y-intercept: -8
domain: (-?, ?)
range: [-9, ?)
