In the year 2007, the age-adjusted death rate per 100,000 Americans for heart disease was 233.9. In the year 2012, the age-adjusted death rate per 100,000 Americans for heart disease had changed to 190.7.
a) Find an exponential model for this data, where t = 0 corresponds to 2007.
f(t) =
b) Assuming the model remains accurate, estimate the death rate in 2037. (Round to the nearest tenth.)
