Function: is a relation meaning each domain will have a range.

The graph on the left shows the domain of language classes and the range as the language spoken in class. The independent variable will be the language class and the dependent variable will be the language. This graph shows that each domain (spanish class, cantonese class, french class, and german class) will have one range ( spanish, cantonese, french and german).

The graph on the right shows the same thing as the left but there is one domain that have two ranges. Which is called a relation. Cantonese class have Cantonese and French being spoken.

16/20 - Please talk about the independent and dependent variables. Also fix this phrase "The graph on the right shows the same thing as the left but there is one domain that have two ranges. Which is called a relation."
