How do you identify the independent variable in a function?

Back

The independent variable is the one that is manipulated or changed in an experiment or equation, often represented on the x-axis in a graph.

Front

What is the dependent variable in the equation y = x - 6?

Back

The dependent variable is y, as its value depends on the value of x.
