FUNCTIONS

This week we learned about functions and how to tell if a relation is a function or not.

Functions are considered special relations, where each input has only one output.

Therefore, they are categorized as relations.

Here are some examples of  how to tell if a relation is a function or not.

It comes to the conclusion that if you have only one output for each input, it is a function,

and if you have multiple outputs for an input, it is not a function.

It is the same with other graphs too, and you can easily notice if it is a function or not by figuring out if there is a chance of  y to have two or more values.

I will post more information next week.
