Let  g(x) be an ininitely differentiable function , such that  g(2x + 6) = g^′ (3x − 1) for all x.  given that  g(((44)/3)) = 33 .  find   g′′(8)
Letg(x)beanininitelydifferentiablefunction,suchthatg(2x+6)=g(3x1)forallx.giventhatg(443)=33.findg(8)

u=3x−1⇒x=((u+1)/3)⇒2x+6=2×((u+1)/3)+6=((2u+20)/3)  g′(u)=g(((2u+20)/3))  g′′(u)=g′(((2u+20)/3))×(2/3)=(2/3)×g(((2(((2u+20)/3))+20)/3))=(2/3)×g(((4u+100)/9))  g′′(8)=(2/3)×g(((4×8+100)/9))=(2/3)×g(((44)/3))=(2/3)×33=22
u=3x1x=u+132x+6=2×u+13+6=2u+203g(u)=g(2u+203)g(u)=g(2u+203)×23=23×g(2(2u+203)+203)=23×g(4u+1009)g(8)=23×g(4×8+1009)=23×g(443)=23×33=22
