The independent variable is the one where you control the values.
The dependent variable takes on values based on what you decide to set the independent variable's values.
.
Usually, we define the independent variable as 'x'.
The dependent variable depends on the value of 'x' so we say it is a function of 'x', which is f(x).
That means we show the dependent variable's values on the y-axis.
.
Examples:
f(x) = x
f(x) = x + 1
f(x) = x^2 - 1
.
In all these example, f(x) is the dependent variable and x is the independent variable.
