domain
or
range
of a function.

Domain
Range
State the domain and range of this relation:
{ (-3, 2) , (4, 1) , (0, 3) , (5, -2) , (2, 7) }
Domain: {-3, 2, 4, 1} Range: {0, 3, 5, -2, 7}
Domain: {-3, 0, 2, 4, 5} Range: {-2, 1, 2, 3, 7}
Domain: {-2, 1, 2, 3, 7} Range: {-3, 0, 2, 4, 5}
Domain: {0, 1} Range: {-2, 5}
Consider the relation:
{ (-2, -3) , (-1, 4) , (0, 5) , (1, 6) }
Identify the
range
of the relation.
