Answer:

Step-by-step explanation:

the initial population is 500

after it grows 5% in 1  year we will have 500 * 1.05 ^1  because

500 represents 100%  but

after 1 year we have 105% of the 500 people or 500*1.05 = 500 * 1.05 ^1

after 2 year we have 105% of 500*1.05 or 500*1.05*1.05 = 500 * 1.05 ^2

if we generalize

after x year we have 500 * 1.05 ^x

the population is an exponential function of time because the number of population depends on the number of years
