Thread: Average rate of change

Question: "The population, P, of a small town after t years can be modelled by the function p(t)=0.5t^2+150t+1200, where t=0 represents the beginning of this year.

a) Write an expression for the average rate of change of the population from t=8 to t=8+h

b) Use the expression in part a) to determine the average rate of change of the population when h=2.

Thanks in advance!
