Please please PLEASE show steps so I can figure out how to do these in the future. Thanks! Appreciated.

Solution

P\'=F\'(x)G(x)+G\'(x)F(x) F(2)=3 F\'(2)=0 G\'(2)=1/2 (1/2) P\'(2)=3*1/2+0*G(2)=3/2 b)Q\'(x)=(F\'(x)*G(x)-G\'(x)F(x))/(F(x))^2 G\'(7)=-2/3 F\'(7)=1/4 F(7)=6 G(7)=1 Q\'(7)=(1/4*1+2/3*6)/36=(1/4+4)/36=17/144
