Question

The population of a school is 800 students and is increasing at a rate of 2% per year. Write

an exponential growth function, then find the population of the school after 9 years.
Why is it not giving the right answer

Answer 1

After 9 years the population would be 956. The exponential growth function would be
`x(956)=800_(0) (1+(2)/(100))^(9)`

Explanation:

y=a(1+r)x

a = initial amount

r = growth rate as a decimal

x = number of time intervals passed (days, months, years)

y = amount after x time

This formula is used to express a function of exponential growth.
