Find f ' (x) for the function
f(x) = x^2 / x^3 + 4
how to start this and what do f ' mean...
please if you cant help with question tell me what f ' means
Surely you mean $\displaystyle \dfrac{x^2}{x^3+4}$. That is not what you posted.
Now you learn to post correctly if you want proper help.
If $\displaystyle f(x)=\dfrac{g(x)}{h(x)}$ then $\displaystyle f'(x)=\dfrac{g'(x)h(x)-g(x)h'(x)}{[h(x)]^2}$
