This week in math 10 we learned how to identify functions.

Differences between a function and a relation. A function is the X variable paired with the Y variable And each number must be special meaning that there can’t be to X variables that pair with the same Y variable.

The image above is an example of a function because each X value pairs with Y value, with no number being repeated.

The photo above is an example of a relation because two or more X variables have the same pair as the Y variable.
