Answer
Is a function
Domain: {1, 2, 3, 5}
Range: {10, 15, 19, 27}
Work Step by Step
This is a function because there is exactly one y-value for each x-value. To find the domain, we make a set of all possible x-values given by the problem. To find the range, we make a set of all possible y-values given by the problem.
