Best ResponseYou've already chosen the best response.0it says to use the definition, so i think you are supposed to write \[lim_{h>0}\frac{f(x+h)f(x)}{h}=lim_{h>0}\frac{(x+h)^2+(x+h)(x^2+x)}{h}\]

Best ResponseYou've already chosen the best response.0if you just need the answer then angela gave it to you but if you have to write it to hand in you need to use the definition, not the power rule.

Best ResponseYou've already chosen the best response.0\[\frac{x^2+2xh+h^2+x+hx^2x}{h}=\frac{2xh+h+h^2}{h}=2x+1+h\]and now let h to to zero to get your answer.
