Question

What are some examples of range?

Answer 1

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`.
