Question 1: Use simple exponential smoothing to predictions for revenue for the next four quarters. alpha = 0.30

Question 2: Use Trend-Adjusted Exponential Smoothing (Holt's method) to make forecast for revenue during the next four quarters. Assume alpha = 0.05 and beta = 0.65, initial revenue forecast = 1209285.75 and initial trend forecast = 15714

Question 3: Using least-square regression with season index decomposing method, forecast the revenues during the next four quarters.
