Answer:


(dy)/(dx)=-(2xe^(3-x^2))/(e^(3-x^2)+9)

Step-by-step explanation:

We were given the function:


y=\ln\left(e^(3-x^2)+9\right)

We are to find the derivative of this function, we have it shown below:


\begin{gathered} y=\operatorname{\ln}(e^{3-x^(2)}+9) \\ If:y=ln(u) \\ Then:y^(\prime)=(u^(\prime))/(u) \\ y^(\prime)=(dy)/(dy) \\ u=e^(3-x^2)+9 \\ u^(\prime)=-2xe^(3-x^2) \\ y^(\prime)=(u^(\prime))/(u) \\ \Rightarrow y^(\prime)=(-2xe^(3-x^2))/(e^(3-x^2)+9) \\ But:y^(\prime)=(dy)/(dx) \\ (dy)/(dx)=-(2xe^(3-x^2))/(e^(3-x^2)+9) \\ \\ \therefore(dy)/(dx)=-(2xe^(3-x^2))/(e^(3-x^2)+9) \end{gathered}
