Question 1176909: A city had a population of 22,500 in 2007 and a population of 24,300 in 2012.
(a) Find the exponential growth function for the city. Use t = 0 to represent 2007. (Round k to five decimal places.)
I got N(t) = $$22500e−0.01539t for (a) but it was incorrect.
(b) Use the growth function to predict the population of the city in 2022. Round to the nearest hundred.

Hello, your error is seen even by an unarmed eye:
The population is increasing,
while your exponential function describes decrease.
