Best ResponseYou've already chosen the best response.1it just the derivative of a function... u can use the basic formula : y = x^n > y ' = n*x^(n1) y = a (a is constant) > y ' = 0

Best ResponseYou've already chosen the best response.0That's the right answer! Thank you, how come we dont have to use the quotient rule though if i have a fraction?

Best ResponseYou've already chosen the best response.0I'll try to explain why the quotient rule isn't used. What @RadEn described was L'Hopital's rule, which says that the limit of some rational function f(x)/g(x) (a ratio of f to g), where both f and g are differentiable and g(x) is nonzero, is equal to the limit of the ratio of the derivatives of f and g. \[\lim_{x\to c}\frac{f(x)}{g(x)}=\lim_{x\to c}\frac{f'(x)}{g'(x)}\] The quotient rule itself wasn't used because you do not find the derivative for f(x)/g(x), but rather f(x) and g(x) separately.
