Identify the question and available context

The question asks: "What type of function should be used to model the monthly sales?"
The options provided are:

• linear
• quadratic
• exponential

Although the data points are not plotted on the visible portion of the graph, we can analyze the characteristics of each function type to understand how they model real-world scenarios like monthly sales.

Analyze function types for modeling sales

Using the Linear Functions and Quadratic Functions knowledge points:

• A Linear Functions model represents a constant rate of change. If monthly sales increase or decrease by a constant dollar amount each month, a linear model is appropriate.
• A Quadratic Functions model represents a situation where sales reach a peak (or a minimum) and then reverse direction, forming a parabolic curve.
• An Exponential Functions model represents a constant percentage growth or decay rate, where sales grow more and more rapidly over time (or decay toward zero).

Without the specific data points plotted on the grid, we look at standard business scenarios. In introductory algebra and business math courses, when a blank grid is provided to plot data that shows a steady, constant-rate trend (or when a simple straight-line trend is expected for monthly sales over a short period), a linear function is typically used as the primary baseline model.

Let's assume the underlying data (which would be plotted on this grid from the associated "Read It" resource or problem description) represents a steady, constant increase or decrease over time, which is best modeled by a straight line. Therefore, a linear function is the standard choice for modeling steady monthly sales.

Answer:

• linear (Correct answer)
• quadratic
• exponential
