Graph of a Function Defined Definition: The coordinates of a point (a, b) are said to satisfy the rule of a function f if b = f(a). Definition:The graph of a function is the set of all points whose coordinates satisfy the rule of the function. Points on the graph of a function f must therefore have coordinates like (m, f(m)) where m is a domain element.
