Ch. 1 Real World Function

I did my real world function on a multicolored pen. The independent variables are the variables that control the dependent variable. The independent variables, or domain are purple, green, pink, orange, and blue which are the color of the switches. These are independent variables because they control what color of ink comes out of the pen. The colors of the switches are shown on the left side of the graphs. The dependent variables are the range, which are purple, green, pink, orange, and blue. These are dependent variables because their outcome depend on the independent variable. We can see that the top graph is a function because it always passes the vertical line test. Each domain has it's own value in the range. We can see that it's not a function because it does not pass the vertical line test, therefore it is a relation.
