The

**domain**for this function is (0, 1, 2) which is the type of hair clippers.The

**range**is (0,1,2) which is the setting of the type of hair clipper used on a person's head.The

**independent variable**in the graphs is the type of hair clip/comb used.The

**dependent variable**in the graphs is the type of hair clip/comb used that appears on a person's head.The definition for a

**function**is*a relation for which each element of the domain corresponds to exactly one element of the range*.- The graph on the left is a function because for every x-value, only 1 y-value responds and it passes the vertical line test.

The definition for a

**relation**is*a set of ordered pairs*.- The graph on the right is a relation. This graph is only a relation and not a function because the x-value hits the graph at 2 point which shows that it didn't pass the vertical line test.
