Evaluate each function composition.

Enter each answer as a whole number (like -4, 0, or 253).

When x=2\displaystyle {x}={2}, g(f(x))\displaystyle {g{{\left({f{{\left({x}\right)}}}\right)}}}=

When x=2\displaystyle {x}={2}, f(g(x)+1)\displaystyle {f{{\left({g{{\left({x}\right)}}}+{1}\right)}}}=

When x=2\displaystyle {x}={2}, h(g(x)+3)\displaystyle {h}{\left({g{{\left({x}\right)}}}+{3}\right)}=
