Case Study

Comparing Inventory Demand Forecasting Models

Based on the provided scenario, answer the following questions to demonstrate your understanding of the graphical relationship between the two forecasting models:

  1. State the standard yy-coordinates obtained by the point-plotting method for the baseline model f(x)=2xf(x) = 2^x at the xx-values -1, 0, and 1.
  2. State the corresponding yy-coordinates obtained for the accelerated model g(x)=2x+1g(x) = 2^{x+1} at the same xx-values (-1, 0, and 1).
  3. Describe the horizontal translation that occurs to the graph of f(x)=2xf(x) = 2^x to produce the graph of g(x)=2x+1g(x) = 2^{x+1}, specifying both the direction and the number of units.
