dependent variable
[dependent variable|dependent variable] The dependent variable is y, denoted as the output of a function.
Definition
dependent variable The dependent variable is y, denoted as the output of a function. The independent variable is x, denoted as the input of a function. The dependent variable is the inverse of the independent variable in this context.
Mechanism
dependent variable The inverse function is denoted by swapping x and y roles, typically using x for independent and y for dependent variables. This representation aids in graphing functions and their inverses on shared axes.
Examples
dependent variable For example, consider the function f, where the domain is the set D = {1, 2, 3} and the rule is f(x) = 3 --.x.
