As you get to harder and higher analysis of functions, it's not required.
A function rule, apparently, is an equation that represents a function.
A function, properly defined, is its graph. A graph is a subset of a plane, where it's the set of all points (a, b), and for every value a, f(a) = b is the definition of a function.
So you can get a plane, squible some lines that's not over lapping, you get a function. How the HELL do you get an equation for that? Hence, the function is kinda useless?
No! Function equations can help us making analysis of those that does have one. In terms of derivatives, limits etc.

You need to give an example of the rule and the function you want.

A rule is a way of describing a function in words. Conversly, a function is simply a way of describing mathematical rules in numbers and symbols.
A table organizing to imput rule and output of a function
The rule of a function in math is what relates the input value to the output value. For example, if f(x) = x2, the "function rule" is to square the input value to get the output value.
Only the function rule. Very complicated patterns may be impossible to discern from a scatter plot or table.
