​Names for Domain

• ​D = Domain

• ​I = Input

• ​X = x-values

• ​I = Independent Variable

​Names for Range

• ​R = Range

• ​O = Output

• ​Y = y-values

• ​D = Dependent Variable

Multiple Choice

Which is the set of all y-values or the outputs?

• Domain

• Relation

• Range

• Function

Multiple Choice

What is the domain of a relation?
