Find the derivative for the following function: ln (absolute value of) -8x^2 +6x

OpenStudy (anonymous):

Use chain rule.

OpenStudy (anonymous):

Could you tell me where you are stuck?

OpenStudy (credmond):

I'm not really sure how to start :/

OpenStudy (anonymous):

Okay, so do you know how to find the derivative of \[ f(g(x)) \]

OpenStudy (credmond):

mhm!

OpenStudy (anonymous):

let \(f(x)=|x|\) and let \(g(x)=-8x^2+6x\)

OpenStudy (credmond):

ohhh okay!

OpenStudy (credmond):

how do we find the derivative of an absolute value?

OpenStudy (anonymous):

\(|x| = \sqrt{x^2}\)

OpenStudy (anonymous):

Could you find the derivative of this?

OpenStudy (credmond):

ohhh okay yeah gotcha!
