Determine whether the relation represents a function. If it is a function, state the domain and range. {(19, - 4). (3, - 3), (3, 0), (12, 3), (28, 5)} O A. function domain: {19, 12, 3, 28} range: {- 4, - 3, 0, 3, 5} O B. function domain: { - 4, - 3, 0, 3, 5} range: {19, 12, 3, 28} O C. not a function
