Answer: Depends on the orders pairs
Step-by-step explanation: You didn’t include the ordered pairs so I’ll just do an example.
(1,5). (2,11). And(6,13) Theese orders pairs represent a function because, there are no repeating X values.
(2,5) (2,10) and (5,45)
Theese ordered pairs do NOT represent a function because, the X values repeat.
A function can be linear and nonlinear, they can have repeating Y values but NO repeating X values.
A trick for this is to put a piece of paper and cover sections and see if your line “turns back”.
