Determine Whether the Graph Is That of a Function

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|-2 ≤ x ≤2}
Range: all real numbers
Intercepts: (-2, 0) , (2, 0)
Symmetry: x-axis, y-axis

B) function
domain: all real numbers
range: {y|y ≤-2 or y ≥ 2}
intercepts: (-2, 0) , (2, 0)
symmetry: y-axis

C) function
domain: {x|x ≤-2 or x ≥ 2}
Range: all real numbers
Intercepts: (-2, 0) , (2, 0)
Symmetry: x-axis, y-axis, origin

D) not a function
