I am very confused on this question and how to solve it please help. Blue whales are an endangered species due to harpooning and hunting that began in 1900. Up until the1960s it is estimated that 99% of the blue whale population was killed. Since then, whale harpooning hasbecome illegal in most countries. Because of this, numbers have started to rise again.In 1979, 700 whales were reported off the coast of California. In 1996, 2580 whales were reported off thecoast of California. The Law of Uninhibited Growth applies to this situation. Using the above data, find afunction of the form N(t) = N0e^kt which models the number of whales t years after 1979. (Use t = 0 to represent the year 1979.)
