The relation is a function. Domain: {$2,3,5$} Range: {$5,7,9,11$}
In a function, no two ordered pairs can have the same first component and different second components. Since no two ordered pairs in the question have the same first component and different second components, this means that the relation is a function. The domain is the set of x-values: {$2,3,5$}. The range, on the other hand, is the set of y-values: {$5,7,9,11$}.
