Question

Use the description of a scenario below to answer the following problem. Note: this is identical to the scenario described above.

Organic waste deposited into a lake will cause a decrease in the oxygen
concentration in milligrams per liter of the water. Assume organic waste is
deposited into the lake at year t=0 and the oxygen concentration is
modeled by O(t)=t3−3t2+22 for three years following the event.

----

What is the non-zero value of t that maximizes the oxygen concentration in the lake between years t=0 and t=3?

t=2 years

t=5 years

t=3 years

t=1 year

t=0 years
