Moreover, the variable is one of the quantities which show variation as per the performed mathematical operation. Referencing the above example, if the independent variable, x, is equal to 12, we can write this in function notation as f(12), and can compute the dependent variable as follows: In this function, f(x) is always 7 less than x. In contrast, the dependent variables describe function outcome variables. The "output" value of a function. However, this is not necessarily the case, hence the experiment.
