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: all real numbers
range: all real numbers
intercept: (0, -3)
symmetry: none
B. function
domain: {x|x = 2 or x = -3}
range: all real numbers
intercept: (-3, 0)
symmetry: x-axis
C. function
domain: all real numbers
range: {y|y = 2 or y = -3}
intercept: (0, -3)
symmetry: none
D. not a function
