Parent functions !

ABC_123

what is the precise definition of "parent functions" ?

I know that : f(x)=x ,f(x)=x^2 , f(x)=sqr(x) , f(x)=1/x , f(x)=|x| are parent functions but what about Rational functions?
what is the parent function of the Rational functions ?

Do you perhaps mean functions that have not yet been integrated or derived?

Also, please don't type in all caps. It's giving me a headache.

You can always report these things. I'll remove the caps.

I didn't know that, I'll keep it in mind.
