The population of knoxville is 500,000 and is increasing at the rate of 3.75% each year. approximately when will the population reach 1 million?

Dp/dt = .0375 people/year

ln p = .0375 t + c 

p = c e^(.0375 t) 
when t = 0, p = 500,000 
so 
p = 500,000 e^(.0375 t) 

so 
2 = 1,000,000/500,000 = e^(.0375 t) 
ln 2 = .0375 t 

t = 18.5 years

The question is asking to determine if the said function that represent the price of the product and base on the research, the answer would be that the function is Decreasing because 0.63, the number inside of the parenthesis, is less than the number 1.
