Question

Part 1: Create a relation of five ordered pairs that is a function. In complete sentences explain why this relation is a function.
Part 2: Create a relation of five ordered pairs that is not a function. In complete sentences explain why this relation is not a function

Answer 1

(1,2), (2,3), (3, 4), (5, 6), (6,7)

This is a function because each input has exactly one output (input, output)

(1,1), (1, 2), (3, 4), (5, 6), (6,7)

This is not a function because 1 is mapped to TWO different values (1 and 2) which means it's not a function
