Analyzing and Graphing Exponential Inventory Turnover Models
You are a trainee data analyst at a regional logistics and supply chain company. Your department is analyzing the efficiency of two different inventory turnover models. The remaining stock level fractions over time (in weeks) are represented by the exponential functions and g(x) = \left(\frac{1}{3} ight)^x.
To present these models at the next team meeting, you need to explain how to graph both functions on the same coordinate system using the point-plotting method. Write a short explanation addressing the following key features of the graphs:
- Identify the shared -intercept for both and as a coordinate pair, and explain mathematically why both graphs must pass through this point.
- Describe the direction of both curves as they move from left to right (increasing ), and explain how the bases of the functions ( and ) dictate this direction.
- Compare the rate of decrease for the two functions when . Specifically, identify which function decreases more rapidly and verify this by comparing their values at .

In a technical report comparing two different decay models, the functions and are plotted on the same coordinate system. According to the properties of these functions, which specific point on the coordinate system is shared by both graphs?
A logistics manager uses the functions f(x) = \left(\frac{1}{2} ight)^x and g(x) = \left(\frac{1}{3} ight)^x to model the rate of depletion for two different fuel types. True or False: When graphing these functions on a coordinate system, both curves will decline (go down from left to right) because the base of each function is between 0 and 1.
