Independent & Dependent Variables
Independent Variables
An independent variable is a variable in an equation, whose values compose the domain. An independent variable may have its value freely chosen regardless of the values of any other variable.
For example: In the equation , the independent variable is x . The variable y is not independent, because it depends on the value chosen for x .
For example: In the equation , the independent variable is x . The variable y is not independent, because it depends on the value chosen for x .
