Can you guess my name, first correct answer gets 10 points?<<>>!?

The domain of a function is part of its definition So, from the correct mathematical standpoint, it doesn't make sense to ask what the domain of a function is. But, assuming this function is defined on the reals, then, since the numerator is continuous, f makes sense for every real x that doesn't zeroe the denominador. Since the denominator vanishes if and only if x = -1, then the largest set the domain can be is D = R - {-1}.

Assuming this is the domain, observe that, for every x in D, f(x) = ((x- 1)(x + 1))/(x + 1) = x - 1. So, its not true that the range is R, because f doesn't assume the value -2. Simply because -1 is not in D.

But we readily see f assumes all reals distinct from -2. So, the range is R - {-2}.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
