Functions- Open Middle Problems

Using the Integers 0-9 (and only each Integer once), create a set of ordered pair that represents a Function.

 

f(x) = (    ,    ),(    ,    ),(    ,    ),(    ,    ),(    ,    )

Graph the Ordered Pairs

Using the Rational Numbers 0-9 (and only each once), create a set of ordered pair that does not represents a Function.

 

(    ,    ),(    ,    ),(    ,    ),(    ,    )
