Chapter 2.4, Problem 30ES

Find $F^{\prime }\left(\pi \right)$ given that $f\left(\pi \right)=10,f^{\prime }\left(\pi \right)=-1,g\left(\pi \right)=-3$ , and $g^{\prime }\left(\pi \right)=2$ .

(a) $F\left(x\right)=6f\left(x\right)-5g\left(x\right)$

(b) $F\left(x\right)=x\left(f\left(x\right)+g\left(x\right)\right)$

(c) $F\left(x\right)=2f\left(x\right)g\left(x\right)$

(d) $F\left(x\right)=\frac{f\left(x\right)}{4+g\left(x\right)}$
