In its simplest form, the domain is all the values that go into a function, and the range is all the values that come out.
So if you input {–3, 1, 4.5} for x what will you get out for y

--------
f(-3) = -(-3)+1 = 3 + 1 = 4
f(1) = -1+1 = 0
f(4.5) = -4.5 + 1 = -3.5
---------
Range:: {4,0,-3.5}

Comment:
Finding the domain.
1st: Assume the domain is All Real Numbers.
---
2nd: Look for elements of the Rule which would restrict the domain, such as::
a) even roots of a variable expression; it must be >= zero
b) a variable expression in a denominator; it cannot equal zero
c) log or ln of a variable expression; it must be >= zero
-------------
If the Rule you have does not have a or b or c,
the domain is All Real Numbers.
