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
![indep_var_1 indep_var_1](https://claregladwinresd.glk12.org/pluginfile.php/2261/mod_book/chapter/4220/Linear/images/indep_var_1.png)
Example What is the independent variable in the function
?
![indp var 2 indp var 2](https://claregladwinresd.glk12.org/pluginfile.php/2261/mod_book/chapter/4220/Linear/images/indp_var_2.png)
The independent variable in the given equation is x.
