A function is a relationship between quantities (variables) that occurs when the value of one of the quantities can be given uniquely by specified values of the other quantities. The variables involved can be either independent or dependent. The values of certain variables are fixed while others are allowed to change. The fixed variables are called the independent variables, and the dependent variables are those that change in response to the given value of the independent variable. A function therefore relates dependent variables to independent variables, the only restriction being that each value of the dependent variable is given uniquely by one, and only one, value for each of the independent variables.

Function notation is important because it helps to clearly communicate how a function operates by providing a compact and standardized way to represent mathematical relationships. It allows us to define, manipulate, and analyze functions more efficiently, enabling us to work with complex mathematical concepts in a concise and organized manner. Additionally, function notation aids in describing the input and output of a function, making it easier to understand and apply in various mathematical contexts.
