    There still is no question. Find the Domain? What is to be done?

    I did see the attachement. g(x) is defined and there is no instruction. What is to be done?

    Sorry for didn´t say before. I need to find the derivative.

    There 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?

    May I use the quotient rule first and use the product rule?

    You can do that if you want, but you may become confused as it is more a side-effect of the product rule. You'll need the derivative of that leading fraction, anyway, so it doesn't much matter where you start.

    I'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.

    In this case I will compute the derivatives separately?

    Let's see what you get. Then we can reassemble.

    I will use the property from algebra. a*(b/c)=ab/c

    And the use the quotient rule.
