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: all real numbers intercepts: (-2, 0), (0, 2), (2, 0) symmetry: none B. function domain: {x|x ? -2} range: {y|y ? 0} intercepts: (-2, 0), (0, 2), (2, 0) symmetry: none C. function domain: {x|x ? 0} range: {y|y ? -2} intercepts: (-2, 0), (0, 2), (2, 0) symmetry: y-axis D. not a function
