Isn't this strange!!! Hello, Sometime ago I realized sth strange for most of the polynomials; For example, [tex]y=x^2[/itex] if we take f(x+d) as a multiple of f(x), I mean: f(2)/f(1) = 4 hence 4*f(1) = f(2) so 4 is a multiple of f(1). Now; [tex](x+d)^2/x^2[/itex] as x approaches infinity the multiple approaches 1 ! doesn't this means that when y=x^2 and x is an infinitly large number, y reaches a constant term, ie never approaches ininity? I'll be thankfull for your help. I hope I've been able to express what I really mean. Thankyou.
