How do you find the domain and the range of the relation, and state whether or not the relation is a function (0,1), (3,2), (5,3), (3,4)?

Domain: 0, 3, 5
Range: 1, 2, 3, 4
Not a function


When you are given a series of points, the domain is equal to the set of all of the x-values that you are given and the range is equal to the set of all y-values.

The definition of a function is that for every input there is no more than one output. In other words, if you choose a value for x you shouldn’t get 2 y-values. In this case, the relation is not a function because the input 3 gives both an output of 4 and an output of 2.
