can you show that the function defined by f(x,y)=1+a*x+b*y+c*xy is (nearly) a projectivity for large domain and small return values

f_x(x,y)=g*1+a*x+b*y+c*xy

f_y(x,y)=h*1+d*x+e*y+f*xy

for some abcdef,gh

the same as

(x,y)-->(f_x,f_y) is projectivity

or if not possible,

is it nearly the case for large domain and small return values?
