The turnover of legislators is a problem of interest to political scientists. It was found that one model of legislative turnover in a particular body was M(t) = 434e^-0.08t, where M(t) represents the number of continuously serving members at time t. Here, t = 0 represents 1965, t = 1 represents 1966, and so on. Use this model to approximate the number of continuously serving members in each year.

(a) 1969 

(b) 1973
