Write a Function Rule (input/output and dependent/independent)

How to write a #function rule as a two-variable #equation.
Identify the dependent and independent variables. What do you need to do to the independent variable to calculate the dependent?
The input of a function is the independent variable. The output of a function is the dependent variable.
The value of the dependent variable depends on, or is a function of, the value of the independent variable.
An algebraic expression that defines a function is a function rule.
