If the range of a function is (–5, 5), this means that –5 is included in the range, but 5 is not. (The range is said to be “inclusive” of –5 but exclusive of 5.)

Is this true? I've never heard of this before.
Absolutely not.
Square brackets [] are inclusive, round brackets () are exclusive.
So if -5 is included and 5 is excluded, then the range is [-5, 5).
