i’m having trouble with a discussion for my class

“Devon is having difficulty determining if the relation given in an input-output table is a function.

Marco explains to him that in order to tell if the relation in the table is a function, Devon needs to check if any output values are reported. If they repeat and have different input values, the relation is not a function.

INSTRUCTIONS
If Marco is correct, respond to the following statement:
-Summarize Marco’s reasoning in your own words

If Marco is incorrect, respond to the following statement:
-Explain what is wrong with Marco’s reasoning and provide an example of a function.”

please help!!!!!


Sagot :

Marco is right. A function is a pattern that links in a unique way an input value with its output. So if we find different outputs for the same input, we can say that the relation is not a function.
