This is not standard, but I think you might find it useful.
Many of the most important functions are asymptotically equivalent to a function that can be specified in the following ``normal'' form:
where 
for all 
, and 
.
Any function that combines addition, multiplication, logarithm, maximization, or minimization of this type of function can be reduced to this form.
Scalar Multiplication Rule: As an easy starting point, any
positive leading multiplicative constants can be dropped: 
.
