Question

A city population, which was initially 15,500, has been dropping by 3% a year. Write an exponential function and graph the function. Use the graph to predict when the population will drop below 8,000.

Answer 1

15,500(0.03/x) is your equation i believe. the x stands for number of years.It will drop below 8000 after 16 years :)

Answer 2

If it's exponentially, should the equation not be \[8000 = 15500 (-0.03)^{1 }\] ?

Answer 3

sorry , 1 being t representing time
