## One to One Relationships

#### Aligned To Common Core Standard:

**Kindergarten** - Geometry

What are One to One Relationships? Each function works in a different manner and may have different graphical representations. One of the different types of functions is the function with a one-to-one relationship. Just like its namesake, one-to-one relationships in functions mean that they are dependent on each other completely. In other words, if we consider an example y=x+1, then y will change with the value of x. Therefore, for every value of x, the value of y will change. One-to-one functions build a straight line on the graph, while the highest power in the function is 1. In other words, one-to-one functions are linear in nature. These worksheets and lessons help students learn how draw and identify 1 to 1 relationships.
