Question 30 1 pts Exponential smoothing is a time series forecasting technique using weights that decrease exponentially (1 - a) for each past period. More recent results are weighted more heavily. Based on the recursive function of exponential smoothing method, F; = a/i-1 + (1 - a) Ft-1, answer the following two questions. What is the coefficient of the term A__9? a(1-a) 8 O a(1+a) 10 Q a(1+a)^8 O a[1-a) 10 o a{1+a)^2 Question 31 1 pts Question 31 1 pts Exponential smoothing is a time series forecasting technique using weights that decrease exponentially (1 - a) for each past period.
