In the context of a function, the term 'input' refers specifically to the independent variable. This is the value that you provide to the function to determine the output. The independent variable is typically represented by symbols such as \(x\) in the function notation \(f(x)\), where \(f\) is the function and \(x\) is the input value.

When you input a specific value for the independent variable, the function processes that input according to its defined rule or equation to produce an output, often referred to as the dependent variable. Therefore, the independent variable is critical because it sets the stage for all subsequent calculations and outcomes within the function. Understanding that the input is related to the independent variable is fundamental in analyzing functions, as it allows you to manipulate and understand how changes in input lead to changes in output.
