#0, Help no one else seems to be able to give me...

I had a question, and my parents, math teachers, etc. can't help me. Maybe someone here can. I've never done any sort of difficult math (I'm in 9th grade, Algebra 2) and no one can help me with this. I'm not even sure how to notate what I'm asking, but I'll try:
z=x^(y-x)
This is the equation. What I want to know is, for a specified value y, what value of x will make z the biggest? What I want is an equation that, in terms of y, returns the maximum value of z, with x. So, I'm asking, with a set y, what x will make z the biggest. Sorry if you're confused... Thats the only way I know how to explain it.
