You can use function notation as an easy, efficient way of using equations without re-writing them. For example, you can evaluate a function at a certain point:

You can use the notation f(x,y), for example, to define a function with more than one variable:

Defining a function once allows you to use this function within other functions. 

Or, you can combine multiple functions together to create a separate function.
