The number of women in the labor force is expected to increase during the 1990s, but not as dramatically as occurred during the 1970s. One forecasting consultant uses the linear

equation n=4.8 t^{2}-68 t to predict the number of women between the ages of 35 and 44 who will be in the labor force. In this equation, n equals the number of women (aged 35 to 44)who will be in the labor force. (measures in millions) and t equals time measure in year since 1990 (t =0 corresponds to 1990). If n is plotted on the Graph the equation. b. Predict the number of women in this age group who will be in the labor force in 2010, 2015 and 2040.
