• the domain

• a relation

• a function

• the range

What is the domain of a relation?

• the set of all x-values

• the set of all y-values

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

• Domain

• Range

• Relation

• Function

What is the range of the mapping?

• {1, 2, 4}

• {0, 1, 2, 3}

• {0, 3}

• {1, 4}

• {-2, 3, 7}

• [-2, 7]

• {1, 2, 3, 4}

• [1, 4]

What is the range of the table?

• {-4, 0, 1, 3}

• {-2, 0, 2, 3}

• {-4, -2, 0, 1, 2, 3}

• { (0, 0), (2, -4), (3, 3), (-2, 1) }

What is the domain of the relation shown in the table?

• {12}

• {6, 18}

• {3, 9, 15, 16}

• {13}

Is the relation shown a function?

• No, because the x-value 11 is paired with 5 and 8.

• Yes, because each x-value has only one y-value paired with it.

Does the graph represent a function?

• Yes

• No

Is the relation shown in the mapping a function?

• No, because -1 and 4 are pared with 4.

• Yes, because every input is paired with exactly one output.
