Every one of us is all too familiar with the phenomenon of forgetting. Facts that we clearly understood at the time we first learnedthem sometimes fade from our memory by the time the final exam rolls around. Psychologists have proposed several ways to modelthis process. To develop her own model, a psychologist performs an experiment on a group of volunteers by asking them tomemorize a list of 100 related words. She then tests how many of these words they can recall after various periods of time. Theaverage results for the group are shown in the table.TimeWords recalled15 min66.31 h47.18 h39.31 day34.82 days28.93 days27.65 days24.9(a) Use a graphing calculator to find a power function of the form y = atº that models the average number of words y thatthe volunteers remember after t hours.
