The population of Australia in x years after 1980 can be modeled by the function y=14.6*(1.014)^x. Estimate the population of Australia for each year.

a) 1976
b) 1980
c) 1972

I am not sure of what to do. Help Please ?

  • Algebra -

    in 1976, x = -4
    y = 14.6 /1.014^4

    in 1980, x = 0
    anything^0 =1
    y = 14.6

    in 1972, x = -8
    y = 14.6 /1.014^8
