Assume that from 1930 to 1980, the number of deaths from lead poisoning (per 100,000 people) decreased dramatically and could be modeled by f(x) = -0.01487 +542x - 49,275, where x is the year. Determine when, to the nearest year, this death rate was 75 or less by graphing y = f(x) and y=75 in (1930, 1980, 10 by 10, 200, 25)
OA 1964 or after
OB 1960 or after
OC. 1973 or after
OD 1967 or after
