differentiate the following function. you do not need to simplify the derivative.\n\n$f(x)=ln(-8x^{2}-6x + 2)$
Answer
Explanation:
Step1: Apply chain - rule
Let $u=-8x^{2}-6x + 2$, then $f(x)=\ln(u)$. The chain - rule states that $\frac{df}{dx}=\frac{df}{du}\cdot\frac{du}{dx}$.
Step2: Differentiate $\ln(u)$ with respect to $u$
The derivative of $\ln(u)$ with respect to $u$ is $\frac{1}{u}$. So, $\frac{df}{du}=\frac{1}{u}$.
Step3: Differentiate $u$ with respect to $x$
$u=-8x^{2}-6x + 2$, then $\frac{du}{dx}=-16x-6$.
Step4: Calculate $\frac{df}{dx}$
Substitute $\frac{df}{du}$ and $\frac{du}{dx}$ into the chain - rule formula: $\frac{df}{dx}=\frac{1}{u}\cdot(-16x - 6)$. Replace $u=-8x^{2}-6x + 2$ back in, we get $\frac{df}{dx}=\frac{-16x - 6}{-8x^{2}-6x + 2}$.
Answer:
$\frac{-16x - 6}{-8x^{2}-6x + 2}$
