Et $r = \zz[\sqrt{-n}]$ where $n$ is a squarefree integer $> 3$. prove that $2$, $\sqrt{-n}$, and $1 + \sqrt{-n}$ are all irreducible in $r$. \item prove that $r$ is not a ufd. [hint: show that either $\sqrt{-n}$ or $1+\sqrt{-n}$ is not prime.] \item find a non-principal ideal in r.

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
