completely random question about high school
In your experiences in high school, were the teachers and/or administrators sensitive to any change in a student's performance?
ie, If you suddenly started getting C's and D's when a semester before you were a solid A and B student, would the school pull you aside and talk with you, call your parents, or not even notice?
Just trying to get a feel for what is typical....

In high school, yes, teachers would approach students who were performing uncharacteristically in either direction, either to help identify a problem or to congratulate them. (Administrators were detached from the students, except when they had an excuse to discipline someone.)
I don't think that interaction could happen too much in college physics. Since there may only be 2 or 3 exams in a whole semester, it's hard for any given professor to gauge what he should expect from a particular student, and thus notice any change up or down.

Hm I dunno, I'd like to see the solution...
But to me it just looks like Y(1) = 1, Y for any X > 1 is infinite, and Y for any 0<X<1 is also 1 because taking roots of a number less than 1 gives a larger number closer to 1...
This function is undefined for all negative numbers except for X = 1
So I'd just guess that the derivative is zero in the interval (0,1] and undefined everywhere else...
If this is correct, perhaps you could find the derivative in terms of the funtion itself by taking the log of both sides (as you would do for finding the derivative of X^X) and doing a fancy iterative trick but I have no clue... lol
