Using the concepts of dependent and independent variables, it is found that the batteries brand is the independent variable.

--------------------------

In a function, one value of the dependent variable is assigned to each value of the independent variable.
For example, in a function [tex]y = f(x)[/tex], x, which is the input is the independent variable, while y, which is the output, is the dependent variable.
In this question, each brand has a timer, which means that the input is the brand and the output is the timer. Thus, the batteries brand, which is the input, is the independent variable.
