Use the quotient rule to find the derivative.

y = x^2-4 / x


I have done this over and over guys.

Ok I get dy/dx = 1 + 4 / ??? that is the part I am sure of. I don't know if it should be a x or x^2, can someone explain to me how I should know this. Like a rule or something?
 
Write down the "Quotient Rule" for me and let's walk through it.
 
Your formatting is ambiguous. You have posted the following:

. . . . .\(\displaystyle y\,=\,x^2\,-\,\frac{4}{x}\)

But I have a feeling that you might mean the following:

. . . . .\(\displaystyle y\,=\,\frac{x^2\,-\,4}{x}\)

Please reply with clarification. When you reply, please include your answer to the previous tutor's request, showing all of the steps you have tried thus far.

Thank you.

the 1st one and I would appreciate is tkhunny helps me. I dont want to get my info confused by having different people tell me different things.

This is mathematics. It is likely that two folks with a sufficient knowledge base will lead you in the same direction.
 
If you mean \(\displaystyle x^{2}-\frac{4}{x}\), there are a couple fo ways to go about "Using the Quotient Rule." Would you like to do it the way it is, or change it a little so that you might learn a little more?

Your posted guess wasn't very close, sorry.

Take a very close look at the problem statement. It is nto possible to verify your compliance with the problem statement without looking at how you found your answer. If you found the derivative by some other method, have you answered the question correctly?
