Determine whether the relation represents a function. If it is a function, state the domain and range.
-{(-2, 3), (-1, 0), (0, -1), (1, 0), (3, 8)}
A)function domain: {3, 0, -1, 8} Range: {-2, -1, 0, 1, 3} 
B)function domain: {-2, -1, 0, 1, 3} range: {3, 0, -1, 8}
C)not a function

Quizplus · Accepted Answer

A relation is a function if each input (x-value) has exactly one output (y-value). This relation meets that criterion, so it is a function. The domain is the set of all x-values {-2, -1, 0, 1, 3}, and the range is the set of all y-values {3, 0, -1, 8}.
