According to a study, the probability that a smoker will quit smoking increases with the smoker's educational level. The probability (expressed as a percent) that a smoker with x years of education will quit is approximated by the equation f(x) = 0.831x² 18.1x + 137.3 (for 10 ≤ x ≤ 16).t (a) Find f(12).
