Answer:
In the given equation y = f(x) and f(x) = 4x-2, the dependent variable is y.
The dependent variable is the output of the function, and its value depends on the value of the independent variable, which is x in this case. So, when we plug in a value for x, we can calculate the corresponding value of y using the function f(x) = 4x-2. Therefore, y is the dependent variable in this equation.
