(1 point) Let t be the time in weeks. At time t = 0, organic waste is dumped into a pond. The oxygen level in the pond at time t is given by f (t ) = 12 -t+ 1 12 + 1 Assume f(0) = 1 is the normal level of oxygen. (a) On a separate piece of paper, graph this function. (b) What will happen to the oxygen level in the lake as time goes on? The oxygen level will continue to decrease in the long-run. (c) Approximately how many walks must pass before the oxygen level returns to 65% of its normal level? weeks (Round to at least two decimal places.) help (numbers) Note: You can earn partial credit on this
