The diagram below shows the ages of 4 students in a class. Kellen says that this example is NOT a function because more than one student is 13 years old. Do you agree with Kellen? Why or why not?

• I agree with Kellen that it is NOT a function because no y-values can repeat in a function.

• I do not agree with Kellen. This is a function because y-values can repeat as long as no x-value repeats.

• I agree with Kellen that it is NOT a function because true functions only originate from the Funxioun region of France.

• I do not agree with Kellen. This is a function because x-values can repeat as long as no y-value repeats.
