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: {y|y ? 9}
intercepts: (0, -4), (8, 0), (0, 2)
symmetry: none
B. function
domain: {x|x ? 9}
range: all real numbers
intercepts: (-4, 0), (0, 8), (2, 0)
symmetry: y-axis
C. function
domain: all real numbers
range: {y|y ? 9}
intercepts: (-4, 0), (0, 8), (2, 0)
symmetry: none
D. not a function
