I've never heard of the "

*parent function*" before. (Other than changing diapers. (Wink) ) So I Googled it and here is the list I got...

Google

Of particular interest to me, was this site - that at least said, "*There is no such thing as a "parent function." Recently, with increased use of graphing calculators and transformation geometry, math educators have called the most basic functions [those listed on the face of the calculator and some others] parent functions. Functions which include or are derived from these functions are called related functions.*"

"parent function"

Finally, another one of the links gave this answer to the question of what is the parent function for the exponential function...

WikiAnswers - What is the parent function for the exponential function

I honestly don't like this description ("parent function") as I find it confusing and it doesn't really add anything substantive to the field. Calculators differ widely in what functions are listed on their "*face*" and therefore this description is almost useless - if not downright harmful because of its ambiguity.
