Answer:

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-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#.
