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 = 2 or y = -6} intercept: (0, -6) symmetry: none B. function domain: all real numbers range: all real numbers intercept: (0, -6) symmetry: none C. function domain: {x|x = 2 or x = -6} range: all real numbers intercept: (-6, 0) symmetry: x-axis D. not a function
