Determine Whether the Relation Represents a Function

Determine whether the relation represents a function. If it is a function, state the domain and range.
-{(41, -2) , (5, -1) , (5, 0) , (6, 1) , (14, 3) }

A) not a function
B) function
C) function domain: {-2, -1, 0, 1, 3} domain: {41, 6, 5, 14}
Range: {41, 6, 5, 14} range: {-2, -1, 0, 1, 3}
