Question

State the domain and range of the relation { (-3,2),(4,1)(0.3),(5,2),(2,7)} .Then determine whether the relation is a function.

Answer 1

Answer:

Domain: {-3, 0, 2, 4, 5)
Range: {1, 2, 3, 7}

The relation is a function because for every x-value there is one y-value. In other words, for every input there is one output.
