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 ?

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
