Review for Test on Functions

The set of all input values, or x - coordinates , of ordered pairs of a relation is the 

• function
• domain
• range
• mapping

A relation where every input has only one out put is called 

• range
• domain
• function
• mapping

Does the graph represent a function?

• Yes, because the vertical line test shows there are no repeating input values
• No, because the vertical line test shows there are repeating input values

Does this mapping diagram represent a function?

• No, because there are repeating input values
• Yes, because there are no repeating input values

What is the range of the following relation:
(9, -2) (4, 3)  ( 8, 10) ( -4, 8)

• -4, 4, 8, 9
• -2, 3, 8, 10
• (9, -2) ( 4, 3)
• (8, 10) (-4, 8)

• {-2, 3, 7}
• [-2, 3]
• {1, 2, 2, 3, 4}
• [1, 4]

• Function
• Not a Function
