You are calculating a demand forecast using exponential smoothing for time period $t.$ Which of the following is true?

A higher smoothing constant $()$ places more emphasis on demand from time period $t-2$ than $t-1$

A higher smoothing constant $()$ places more emphasis on demand from time period t $-1$ than t $-2$

Changing the smoothing constant does not affect the demand forecast

All of the above

None of the above
