Answer:
Only Table A and E are functions.
Explanation:
Given the relations shown on the tables, we want to determine which of the tables represent a function.
Recall that for a function, one input cannot produce more than one distinct output.
That is a particular input cannot have 2 or more different outputs.
Applying this rule, only the first and the last tables do not have an input generating more than one output.
Therefore, Only Table A and E are functions.
