Solve the problem.Assume that from 1930 to 1980, the number of deaths from lead poisoning (per 100,000 people) decreased dramatically and could be modeled by 
where x is the year. Determine when, to the nearest year, this death rate was 150 or less by graphing y = f(x) and 
in [1930, 1980, 10] by [0, 200, 25].
