I am working on quadratic inequalities and in one of my problems one of the answers is -36.96 people and 13.04 people, obviously you round but can it be a negative amount of people?
You will often get rediculous answers like this - you just discard the negative one becasue it is not in the domain.
I mean the number of people must be greater or equal to 0.
I am talking generally - you need to think of the individual question.
