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|y ? -3 or y ? 3} intercepts: (-3, 0), (3, 0) symmetry: y-axis B. function domain: {x|-3 ? x ? 3} range: all real numbers intercepts: (-3, 0), (3, 0) symmetry: x-axis, y-axis C. function domain: {x|x ? -3 or x ? 3} range: all real numbers intercepts: (-3, 0), (3, 0) symmetry: x-axis, y-axis, origin D. not a function
