Which table represents a relation that's a non-function?
1 answer:
Answer:
The table in the attachment is the right option
Step-by-step explanation:
A table that represents a function must have exactly one y-value assigned to every x-value. In other words, a table that is a function cannot have any x-value (input) with two corresponding different y-values (outputs).
The table in the attachment below represents a relation that is non-function because it has two outputs, 5 and 7, that are assigned or corresponding to one input, 7.
