$f(0,0,0)=0,\, f(0,0,1)=0,\, f(0,1,0)=1,\,  f(0,1,1)=1,\, f(1,0,0)=1,\, f(1,0,1)=1,\,  f(1,1,0)=0,\, f(1,1,1)=0 \,.$\\  We want to derive the ANF of $f$, $f$.  We know that it is  something like $$f (x, y, z) = axyz + bxy + cxz + dzy + ex + f y + gz + h,$$  %  for some $a, b, c, d, e, f, g, h \in \Fb$.
