Let f (t) measure the level of oxygen in a pond, where f (t) = 1 is the normal(unpolluted) level and the time t is measured in weeks. When t = 0, organic waste isdumped into the pond, and as the waste material oxidizes, the level of oxygen in thepond is f(t)=\frac{t^{2}-t+1}{t^{2}+1} What percent of the normal level of oxygen exists in the pond after 1 week? After2 weeks? After 10 weeks? What is the limit as t approaches infinity?
