Question

In 1987, the Australian humpback whale population was 350 and has increased at a rate of about 14% each year since then. Write a function to model population growth. Use a graph to predict when the population will reach 20, 000.

Answer 1

#1) Write a function to model population growth. Use a graph to predict when the population will reach 20, 000.

Answer: In this case what you have to do is use an exponential growth equation. In short the correct function that will model this population growth of 14% each year is P(t) = 350(1.14)^t and the population will reach 20,000 in about 31 years.

I hope it helps, Regards.
