Best ResponseYou've already chosen the best response.0There still is no question. Find the Domain? What is to be done?

Best ResponseYou've already chosen the best response.0I did see the attachement. g(x) is defined and there is no instruction. What is to be done?

Best ResponseYou've already chosen the best response.0Sorry for didn´t say before. I need to find the derivative.

Best ResponseYou've already chosen the best response.0There it is! A problem statement. Okay, that's rather tedious. How do you propose we approach it?  Divide the front?  Multiply through the parentheses?  Jump right in with the Product Rule?  Other?

Best ResponseYou've already chosen the best response.0May I use the quotient rule first and use the product rule?

Best ResponseYou've already chosen the best response.0You can do that if you want, but you may become confused as it is more a sideeffect of the product rule. You'll need the derivative of that leading fraction, anyway, so it doesn't much matter where you start.

Best ResponseYou've already chosen the best response.0What do you suggest?

Best ResponseYou've already chosen the best response.0I'm tempted to do it in chunks. \(\dfrac{d}{dx}\dfrac{x^{3}+1}{x^{3}+3} = ??\)  Usng the Quotient rule. \(\dfrac{d}{dx}\left(x^{2}  \dfrac{2}{x}+1\right) = ??\)  Using the Polynomial rule. Once we get this piece out of the way, the rest will be algebra.

Best ResponseYou've already chosen the best response.0In this case I will compute the derivatives separately?

Best ResponseYou've already chosen the best response.0Let's see what you get. Then we can reassemble.

Best ResponseYou've already chosen the best response.0I will use the property from algebra. a*(b/c)=ab/c
