Based on information provided by the US Institute on Drug Abuse, the percent y of 18 to 25 year olds who had used hallucinogens between 1974 and 1991 can me modeled by the function y= .025x^3-.7x^2+4.43x+16.77, where x=0 corresponds to the year 1974. In what year did the type of drug reach its minimum?
