Ordered+Pairs+Quick+Check

Quick check… Do you think the sets of ordered pairs represent functions? Why?



1) Function: Although there is a repeating x-value (3), the corresponding y-value (11) is also repeating.

2) Not a Function: There is a repeating x-value (3) that has two different y-values.

3) Function: There are no repeating x-values. There can be multiple x-values for a single y-value.
