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.

Question

A. function
domain: {x|-2 ? x ? 2}
range: all real numbers
intercepts: (-2, 0), (2, 0)
symmetry: x-axis, y-axis
B. function
domain: {x|x ? -2 or x ? 2}
range: all real numbers
intercepts: (-2, 0), (2, 0)
symmetry: x-axis, y-axis, origin
C. function
domain: all real numbers
range: {y|y ? -2 or y ? 2}
intercepts: (-2, 0), (2, 0)
symmetry: y-axis
D. not a function
