Evaluate each function composition.

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

When x=0\displaystyle {x}={0}, g(f(x))\displaystyle {g{{\left({f{{\left({x}\right)}}}\right)}}}=

When x=0\displaystyle {x}={0}, f(g(x)+1)\displaystyle {f{{\left({g{{\left({x}\right)}}}+{1}\right)}}}=

When x=0\displaystyle {x}={0}, h(f(x)2)\displaystyle {h}{\left({f{{\left({x}\right)}}}-{2}\right)}=
