The set of all x-values of a relation.

• Any set of data.

• Domain

• A relation where x-values do not repeat.

• Function

• The set of all x-values of a relation.

• Range

• The simplest form of a function.

• Parent Function

• The set of all outputs of a relation.

• put a closed dot on 2 and to the left
• put an open dot on 2 and to the right
• put an open dot on 2 and to the left

Which graph matches the inequality
r ≥ -6?

• A
• B
• C
• D

What inequality is graphed?

• 2 < x ≤ -3

• 2 < x < -3
