Domain: 
Range: 
The relation is not a function.
Explanation:
The coordinates 
are plotted in the graph. The image of the graph is attached below.
The domain of a relation is the set of all x-values for which the function is well defined. Thus, the domain are
The range of a relation is the set of all y-values obtained by substituting the values for x in the function. Thus, the range are
The relation is not a function since, -4.7 has two different y-values. By definition of function, the function cannot have two different y-values for the same x-value.
