Final answer:
Regression models, trend models, and exponential smoothing techniques are commonly used for forecasting demand for new products and services.
Step-by-step explanation:
Regression models, trend models, and exponential smoothing techniques are the most likely techniques to be used for forecasting demand for new products and services. Regression models use historical data to identify relationships between variables and predict future demand. Trend models analyze the general direction and pattern of demand over time. Exponential smoothing techniques use weighted averages to forecast future demand based on past data.
