Domain and Range

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range.

• D: {1, -3, -4,}
  R: {0, 1, 2, -4}
• D: {-4, 0, 1, 2}
  R:{-4, -3, 1}
• D: {0, 1, 2, 3, 4}
  R:{1, -3, -4}
• D: {0, 1, 2, -4}
  R: {1, -3, -4, 1}

A set of ordered pairs is called what?

• 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

• {-2, 3, 7}

• [-2, 7]

• {1, 2, 3, 4}

• [1, 4]

Which relation does the mapping show?

• {(0, 1), (1, 2),(3, 4)}

• {(1, 0), (2, 1), (2, 2), (4, 3)}

• {(0, 1), (1, 2), (2, 2), (3, 4)}

• {(1, 0), (2, 1), (4, 3)}

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.

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

• {12}

• {6, 18}

• {3, 9, 15, 16}

• {13}

Does the graph represent a function?

• Yes

• No

Which relation is shown in the graph?

• {(4, -5), (0, -1), (-1, 3), (5, 3)}

• {(-5, 4), (-1, 0), (3, -1), (3, 5)}

• {(5, -4), (1, 0), (-3, 1), (-3, -5)}

• {(-4, 5), (0, 1), (1, -3), (-5, -3)}
