$$\displaystyle{f{{\left({x}\right)}}}={x}+{8},{g{{\left({x}\right)}}}=\sqrt{{x}}$$
$$\displaystyle{F}{\left({X}\right)}={\left({f}{o}{g}\right)}{\left({x}\right)}={f{{\left({g{{\left({x}\right)}}}\right)}}}={f{{\left(\sqrt{{x}}\right)}}}=\sqrt{{x}}+{8}$$
$$\displaystyle{\left({f{{\left({x}\right)}}},{g{{\left({x}\right)}}}\right)}={\left({x}+{8},\sqrt{{x}}\right)}$$
