Mat told Sam that for a relation to be a function the input values can repeat but the output values cannot. Sam thought Mrs. Gullikson told him in class that if the output values repeat and have different input values, then the relation is not a function. Explain who is correct.
In you explanation tell who is correct, explain how you know (hint make sure you explain the definition of a function in your answer), and include
an example of a function that they could show to prove they are right. Hint Look at lesson 1.1
