Answer: 
Step-by-step explanation:
The range is the set of output values for the domain (the set of inputs).
- When x=-5, y=
. - When x=0,
. - When x=2,

So, the range is 
Integer, natural, whole, rational, irrational, natural (15/3=5), integer (-12/6=-2), rational, irrational, rational, rational
Natural-the counting numbers (1,2,3,100...)
Whole-all natural AND 0
Integers-add negative numbers (no fractions)
Rational-add fractions and decimals
Irrational-numbers that can’t be a fraction (square root of 3, pi)
Real-all numbers
