What are the domain of the function: {(1, 4), (-2, 3), (-1, -3),

• {-1,2,1}

• {1,-2,-1}

• {4,3,-3}

• {-4,-3,3}

Answer explanation

Domain are the set of x-values, first element in an ordered pair.

What are the range of the function: {(1, 4), (-2, 3), (-1, -3),

• {-1,2,1}

• {1,-2,-1}

• {4,3,-3}

• {-4,-3,3}

Answer explanation

Range are the set of y-values, second element in an ordered pair.

All of the y-values or outputs are called what?

• Domain

• Range

• Ordered Pair

• Relation

Answer explanation

Range is also called the y-values or output of a function.

All of the x-values or inputs are called what?

• Domain

• Range

• Ordered Pair

• Relation

Answer explanation

Domain is also called the x-values or input of a function.

Which relation is NOT a function?

• {(-2,7),(3,7),(4,7)

• (-2,-4),(3,4),(4,4)

• (1,-5),(3,1),(-5,4)

• (-5,-1),(3,1),(-5,4)

What are the domain of this relation?

• {1,9,0}

• {1,-9,0}

• {1,3,-3,0}

• {1,3,3,-0}

What are the range of this relation?

• {1,9,0}

• {-1,9,0}

• {1,3,-3,0}

• {-1,3,3,0}

A set of ordered pairs (x , y) such that no two ordered pairs

have the same x-value but different y-values.

• Relation

• Function

• Coordinates

• Values

Is the diagram illustrates a function?

• Yes, because all domain have one specific range.

• Yes, because all range have one specific domain.

• No, because a specific domain repeats.

• No, because a specific range repeats.

Is the graph represents a function?

• Yes, passes through the graph once.

• Yes, passes through the graph twice.

• No, passes through the graph twice.

• No, passes through the graph once.
