Answer:
All of the values that can go into a relation or function (input) are called the domain.
All of the values that come out of a relation or function (output) are called the range.
Range may also be referred to as "image".
Note that both relations and functions have domains and ranges.
The domain is the set of all first elements of ordered pairs (x-coordinates).
The range is the set of all second elements of ordered pairs (y-coordinates).
Only the elements "used" by the relation or function constitute the range.
definition
Domain: all x-values that are to be used (independent values).
Range: all y-values that are used (dependent values).
Set Builder notation may be used to express domains and ranges.

Domain: all x-values that are to be used (independent values).
Range: all y-values that are used (dependent values).
Set Builder notation may be used to exp-restate the appropriate domains for the functions shown below.
When functions are expressed as "rules" (formulas), be sure to think about possible "problem" spots before stating the domain. Remember that the domain is the x-values that are allowed by the function's equation. In most cases, a graph will help show the domain.
