There really is no such thing as a "Parent Function." It is a made-up notion to help teachers describe how to use graphing calculators and the like. I suppose in that context the parent function for logarithms would be either
or
With a decided preference for the latter in my mind.
You can put this solution on YOUR website! What is the parent function of a logarithm?

While I have never heard of a "parent function",
the answer might be y = log(x). Using it you
can figure out the graph of y = 3log(2x+5) -3
by shifts, stretches, etc.

You can put this solution on YOUR website! maybe it's an exponential function? or an exponent?
maybe an infinite series?

It's a silly question, give a silly answer - cattle.
