So I did my real world function on coins and the value of the coins. The

**Independent Variables**are the

**Domain**which is demonstrated by the name of the coin in this graph and the

**Dependent Variables**are the

**Range**which is the value in this case. The graph on the right is the Function graph and on the bottom it is a Relation graph. To tell the difference between 2 graph is rather if the graph passes the vertical line test which in this graph the dotted lines. Clearly we could see the bottom graph doesn't pass because the coins represented both value which could never happens. So when the graph doesn't pass it will be a Relation for Graphs that does pass it is a Function.
