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|-5 ? x ? 5} range: {y|-5 ? y ? 5} intercepts: (-5, 0), (0, -5), (0, 0), (0, 5), (5, 0) symmetry: origin B. function domain: {x|-5 ? x ? 5} range: {y|-5 ? y ? 5} intercepts: (-5, 0), (0, -5), (0, 5), (5, 0) symmetry: x-axis, y-axis, origin C. function domain: {x|-5 ? x ? 5} range: {y|-5 ? y ? 5} intercepts: (-5, 0), (0, -5), (0, 5), (5, 0) symmetry: x-axis, y-axis D. not a function
