Which graph does NOT pass the vertical line test?

• Graph 1
• Graph 2
• Graph 3
• Graph 4

Which graph passes the vertical line test?

• Graph 1
• Graph 2
• Graph 3
• Graph 4

Which set of ordered pairs is a relation AND a function?

• {(1,2), (2,3), (2,4)}
• {(1,2), (2,2), (3,2)}
• {(1,2), (1,3), (1,4)}
• {(1,5), (5,1), (1, 1/5)}

{(1,2), (6,4), (X, 5)}
In order for this relation to NOT be a function X must equal what?

• 1
• 2
• 3
• 4

Which set is a relation but NOT a function?

• {(1,2), (2,2), (3,5), (6,7)}
• {(1,1), (1,3), (1,5), (1,8)}
• {(-6,5), (7,8), (8,0), (6,5)}
• A horizontal line

All of the x values or inputs are called what?

• Domain
• Range
• Relation
• Function

All of the y values or outputs are called what?

• Domain
• Range
• Relation
• Function

In the given relation, what domain value corresponds to the range value -2?
{(-1,2), (-2,4), (2,5), (0,-2), (2,0)}

• -2
• 0
• 2
• 4

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.
• Yes, because each x-value has only one y-value paired with it.
• No, because the x-value 11 has two y-values pair with it.
• No, because each x-value has only one y-value paired with it.

Is this mapping a function or not a function? 

• Function
• Not a Function
