1. The problem statement, all variables and given/known data Consider f(x) = x^3 + 4x^2 − 4x − 16. a) How many possible rational zeros does f(x) have? 1. None 2. Two 3. Ten 4. Three 5. Five 3. The attempt at a solution My first response was answer 4. - Three zeroes. I a) solved for the zeroes on paper b) graphed it on a graphing calculator c) realized that a third degree polynomial can have three zeroes d) answered the next question, asking what the zeroes were, correctly. Apparently I'm misunderstanding the question though, because answer 4 is not correct. So just what is the question asking? I thought it was simply "how many zeroes does it have", but I guess I'm missing something.
