The height of a tree, h, depends on its age, a. The height is a function of age. The function notation is _h_ f( _a_ ).

h = f(a)

Step-by-step explanation:

Function notation is the way of representing a language expression in a mathematical form.  It reduces the information to a precise way form, thereby avoiding some lengthy written explanations.  A mathematical function makes a long explanation to become a simple and short expression.  In this example, the height of a tree is expressed as a function of its age, with a simple function, h = f(a), where 'h' = height of the tree and 'a' = age and 'f' = function.
