$(1$ point$)$ Suppose $y=sin(-4x^2-3x-1).$ We can write $y=sin(u),$ where $u=$ The Leibnitz notation for the chain rule is $\frac{dy}{dx}=\frac{dy}{du}*\frac{du}{dx}.$

The factors are $\frac{dy}{du}=($written as a function of $u)$ and $\frac{du}{dx}=$

Now substitue in the function of $x$ for $u$ to get

$\frac{dy}{dx}=($written as a function of $x).$
