Some types of ranges:
shooting range, stove + oven, range of a weapon, (as verb) to move around, home on the range, etc.

Explanation:

No, but seriously, range is either the set of y-values of a function or the difference between the lowest and highest values of a set of numbers.

For the equation y=3x-2y=3x−2, the range is all real numbers because some value of x can be inputted to yield any real number y (y=RR).
For the equation y=sqrt(x-3), the range is all real numbers greater or equal to 3 (y=RR>=3).
For the equation y=(x-1)/(x^2-1), the range is all real numbers not equal to 1 and -1 (y=RR!=+-1).

For the set of numbers {3, 5, 6, 9, 11}, the range is 8 because 11-3=8.
