what is the relationship between the independent variable and the dependent variable
If an equation shows a relationship between x and y in which the value of y is dependent upon the value of x, y is known as the dependent variable and is sometimes referred to as 'function(x)' or f(x). The final solution of the equation, y, depends on the value of x, the independent variable which can be changed.
Independent variables are values that can be changed in a given equation or experiment. Dependent variables are values that result directly from the independent variable.
