After an advertising campaign, the sales of a product often increases and then decreases. Suppose that t days after the end of the advertising, the daily sales are f(t)=−2t^2 +35t+120 Units What is the average rate of growth in sales during the fourth day, that is from t=3, t=4 ___ units per day What is the instantaneous rate of change in sales when t=2 _____ units per day.
