This is a function because each x value has its own y value.
The domain is all the x values : 1,2,3,4,5
The range is all the y values: 1,2,5,10,15

Stepbystep explanation: To determine whether the relation shown here is a function, it's important to understand that a function is a relation in which each xterm corresponds to exactly one yterm.
Each of the xterms shown here 1, 2, 3, 4, and 5 appears only once so each xterm corresponds to only one yterm. So yes, this relation is a function.
The domain of a relation is the set of all the xterms of the relation. So here, the domain will be the set of all the xterms or {1, 2, 3, 4, 5}.
The range of a relation is the set of all the yterms of the relation. SO here, the range will be the set of all the yterms or {1, 2, 5, 10, 15}.
