Question

The number of cellular
subscribers in the United States in thousands from
1985 to 1991 can be modeled by f (x) = 163x^2 - 146x + 205,
where x is the year and x = 0 corresponds to 1985, x = 1
to 1986, and so on.
(a) Write a quadratic inequality whose solution set
represents the years when there were 2 million
subscribers or more.
(b) Solve this inequality.
