Best ResponseYou've already chosen the best response.0y = 8/x, find the derivative using the limit definition..

Best ResponseYou've already chosen the best response.0all of this will be lim as x>0 (f(x+h)f(x))/h = (2/(x+h)  8/x)/h

Best ResponseYou've already chosen the best response.0well the question actually gives (2,4) , so does the y help?

Best ResponseYou've already chosen the best response.0still doesn't work out.. the thing is that's the problem with the graphs when x is on the bottom.. even if i differentiate it and get 8lnx, i won't be able to find slope for negative x... and i have a feelin the limit is pullin us in that direction

Best ResponseYou've already chosen the best response.0is sqrt just over x or over x2?

Best ResponseYou've already chosen the best response.0ok, and i actually give the wrong question it is y = sqrt (5x 1) at x =2 i will wait :)
