Question

Anyone? Anybody know the answer at all?!

Answer 1

`(f \circ g)(x)=\sqrt{(2(4+\sqrt x))/(5)}=\sqrt{(8+2\sqrt x)/(5)}\\\\ (f \circ g)(9)=\sqrt{(8+2\sqrt 9)/(5)}\\ (f \circ g)(9)=\sqrt{(8+6)/(5)}\\ (f \circ g)(9)=\sqrt{(14)/(5)}\\ (f \circ g)(9)=(√(14))/(\sqrt5)\\ (f \circ g)(9)=(√(70))/(5)\approx41,83`
