D. 
Determine whether the graph is that of a function. If it is, use the graph to find its domain and range, the intercepts, if any, and any symmetry with respect to the x-axis, the y-axis, or the origin.
A. function
domain: all real numbers
range: {y|-1 ? y ? 1}
intercepts: (-?, 0), (- 
, 0), (0, 0), (
, 0), (?, 0)
symmetry: origin
B. function
domain: {x|-? ? x ? ?}
range: {y|-1 ? y ? 1}
intercepts: (-?, 0), (- 
, 0), (0, 0), (

symmetry: origin
C. function
domain: {x|-1 ? x ? 1}
range: {y|-? ? y ? ?}
intercepts: (-?, 0), (-

symmetry: none
D. not a function
