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: {x|-9 ? x ? 9} range: {y|-9 ? y ? 9} intercepts: (-9, 0), (0, -9), (0, 0), (0, 9), (9, 0) symmetry: origin B. function domain: {x|-9 ? x ? 9} range: {y|-9 ? y ? 9} intercepts: (-9, 0), (0, -9), (0, 9), (9, 0) symmetry: x-axis, y-axis C. function domain: {x|-9 ? x ? 9} range: {y|-9 ? y ? 9} intercepts: (-9, 0), (0, -9), (0, 9), (9, 0) symmetry: x-axis, y-axis, origin D. not a function
