Best ResponseYou've already chosen the best response.1I'm not sure, but I think its (x + 1)^2 + 3(x  1) + 5

Best ResponseYou've already chosen the best response.0lol look at what i wrote...f(x1 + 1) = f(x + 0) = f(x) since f(x1) = x^2 + 3x + 5 f(x  1 + 1) = (x+1)^2 + 3(x+1) + 5 got the logic?

Best ResponseYou've already chosen the best response.01 and 1 will be cancelled then there will f(x) I didn't get.

Best ResponseYou've already chosen the best response.0hmmm you get that f(x1 + 1) = f(x) right?

Best ResponseYou've already chosen the best response.0now let a = x1 f(a) = a^2 + 3a + 5 agree?

Best ResponseYou've already chosen the best response.0now like i said f(x) = f(x1 + 1) = f(a+1) therefore f(a + 1) = (a+ 1)^2 + 3(a+1) + 5

Best ResponseYou've already chosen the best response.0substituting will actually make it complicated..let me start again do you get that f[(x1) + 1] = f(x)?
