Best ResponseYou've already chosen the best response.0Are you sure it's x>0+ not y>0+?

Best ResponseYou've already chosen the best response.1hmm, this might also seem to be f(x,y) stuff, multivariables

Best ResponseYou've already chosen the best response.0It means the same: x<0, I'm guessing.

Best ResponseYou've already chosen the best response.0I know the right answer should be 1/x^2 but I can't get there

Best ResponseYou've already chosen the best response.0If you have problems with the algebra, read this pdf: It uses x_0 for x and deltax for y, but otherwise it's the same limit. http://ocw.mit.edu/courses/mathematics/1801scsinglevariablecalculusfall2010/1.differentiation/partadefinitionandbasicrules/session2examplesofderivatives/MIT18_01SCF10_Ses2a.pdf
