To determine which type of function best models the sales data over a 5-week period, we need to consider the pattern of the data points. Generally:
1. **Linear function** is characterized by a constant rate of change (straight line). If the sales data increases or decreases by the same amount each week, a linear function is suitable.
2. **Quadratic function** involves a parabolic shape and is appropriate if the rate of change itself is changing (for example, if sales increase by greater amounts each week).
3. **Cubic function** can model more complex relationships where the rate of change changes in multiple ways, typically resulting in an S-shaped curve.
4. **Exponential function** describes rapid growth or decay, where the rate of change increases (or decreases) multiplicatively rather than additively.
To choose the best option, you would typically look at the sales data to see the pattern in the values over the weeks. If you can provide the specific sales figures, I can help you analyze them to decide the best fit. If you are unable to provide this information, consider the trends—linear for consistent changes, quadratic for accelerating changes, exponential for rapid growth, and cubic for more complex patterns.
