The general exponential growth model is defined as

Where, a is initial value, r is growth rate and x is time.
The initial population of town is 9800 and growth rate is 2%. The population growth model is defined as



Put x=7 to find the estimated population after 7 years.


Therefore the correct option is A.
A=29 theres 29 dots each dot is 1 student
Y = -9x - 10
The dolphin is diving 9 feet per second so the rate of change is -9.
It's also 10 feet below sea level which makes the y-intercept -10
