Best ResponseYou've already chosen the best response.0Identify your composite functions f(a) and g(x) such that 3/(x4) = f(g(x))

Best ResponseYou've already chosen the best response.0ok this is where I have trouble.....will it be 3/u ???? Doesn't look right

Best ResponseYou've already chosen the best response.0That is exactly right. If u = x4 then 3/(x4) = 3/u

Best ResponseYou've already chosen the best response.0so will I add 1 to the u (exponent) to be u^2

Best ResponseYou've already chosen the best response.0Not quite. realize that you basically have \[3 * \frac{1}{u}\] So the derivative of what function of u gives you \(\frac{1}{u}\)?

Best ResponseYou've already chosen the best response.0So it's not that. \(\frac{d}{du}[ln\ u] = \frac{1}{u}\) remember?

Best ResponseYou've already chosen the best response.0not sure what you mean about that?

Best ResponseYou've already chosen the best response.0The derivative of ln x = 1/x right?

Best ResponseYou've already chosen the best response.0ln is the natural logarithm function.

Best ResponseYou've already chosen the best response.0oh, yes it does. Too many rules.....

Best ResponseYou've already chosen the best response.0yeah, you'll get them with practice.

Best ResponseYou've already chosen the best response.0So the anti derivative of 1/x = ln x + C

anonymous

Best ResponseYou've already chosen the best response.0So 3 times the anti derivative of 1/u du = ?

anonymous

Best ResponseYou've already chosen the best response.0ok lost again..... I know we have 3/u or 3 * 1/u would it be 3lnx + c ???

anonymous

Best ResponseYou've already chosen the best response.0It would be 3(ln u) + C, but then you have to plug in what u is.

Best ResponseYou've already chosen the best response.0how about 3 ln\[\left x4 \right\] + C sorry couln't get them all in one line

Best ResponseYou've already chosen the best response.0I have a test next Tue. So I will be asking questions up until then. I am sure I will talk to you again..

Best ResponseYou've already chosen the best response.0I got really good with the derivatives, so my brain still wants to do them.

anonymous

Best ResponseYou've already chosen the best response.0Yeah, I know the feeling. Soon you'll get the hang of going the other way.
