Parametric form or written form of the defining relationship of a function that emphasizes the general form of the rule.
Example
The function
f on the set of real numbers defined by the relation
f(
x) = A
x² + B
x + C is a function defined in general parametric form or general form that in this case is that of a second-degree
polynomial. It is the general written form of a
second-degree polynomial function.
