[MOVED] Finding range set, given function and domain set

[blndcountry2]

How would I do this:

f(x)=3x+2 and then it gives me D={-2,0,2} and it says to find the range of each function for the given domain!

Domain: Stuff that goes in.
Range: Stuff that comes out.

Substitute all those values and compile the results.
