Hi Matthew;
What is/are the question(s)?
Are you trying to establish domain and range?
Is there something else?

g(x) = -3 when x = 3
g(x) = 1 when x = 2
g(x) = 5 when x = 1
g(x) = 9 when x = 0
g(x) = 13 when x = -1
g(x) = 17 when x = -2
 
This can be plotted on a graph and it appears to be linear when you do so.
I will repeat what Vivian said, what do you need?
