In[9]:= f@@@Tuples[{0,1},3]
Out[9]= {f[0,0,0],f[0,0,1],f[0,1,0],f[0,1,1],f[1,0,0],f[1,0,1],f[1,1,0],f[1,1,1]}
or to do all your functions at once:
In[35]:= funcs={f,g,h};
res=Outer[Apply,funcs,Tuples[{0,1},3],1];
Grid@Transpose@res
Out[37]= f[0,0,0] g[0,0,0] h[0,0,0]
f[0,0,1] g[0,0,1] h[0,0,1]
f[0,1,0] g[0,1,0] h[0,1,0]
f[0,1,1] g[0,1,1] h[0,1,1]
f[1,0,0] g[1,0,0] h[1,0,0]
f[1,0,1] g[1,0,1] h[1,0,1]
f[1,1,0] g[1,1,0] h[1,1,0]
f[1,1,1] g[1,1,1] h[1,1,1]
