Function Test Review

Is the relation a function? Why or why not?

• Yes, because it passes the vertical line test.
• No, because an input has more than one output.
• Yes, because each input has only one output.
• No, because numbers are repeating in the data.

Use the mapping to list the ordered pairs. Does the relation represent a function?

• Function, { (3,7), (6,5), (6, 10), (12, 9), (18,10) }

• Not a Function, { (3,7), (6,5), (6, 10), (12, 9), (18,10) }

• Function, { (7,3), (5,6), (10,6), ( 9,12), (10, 18) }

• Not a Function, { (7,3), (5,6), (10,6), ( 9,12), (10, 18) }
