independent variable
[independent variable|independent variable] The independent variable is x, and the dependent variable is y.
Definition
independent variable The independent variable is x, and the dependent variable is y. This function is the inverse of f, and we write x = f. Visit this applet link (http://www.openstax.org/I/grapherrors) to see more about graphs of functions.
Mechanism
independent variable The independent variable is typically denoted by x, and its inverse is represented by swapping x and y in the function's equation. This notation helps when graphing both the function and its inverse on the same axes.
Examples
independent 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.
