The domain of a function consists of your choice of x values that you can use.
The range would be the set of values that are the result of using the domain values.
e.g.
if x = -2 , f(-2) = 3(-2) - 8 = -14
if x = -1 , f(-1) = 3(-1) - 8 = -11
...(x) '
if x = 2 , f(2) = 3(2) - 8 = -2
So the range would be the set of numbers from the f(x)s above.
