**Modeling Data with a Function: A Mathematical Approach**

Introduction

In mathematics, modeling data with a function is a crucial concept that helps us understand and describe the behavior of a given set of data. In this article, we will explore how to model the data provided in the table using a mathematical function.

The Data

The data provided in the table consists of two variables, $j$ and $k$ , with the following values:

$j$	$k$
0	3
5	28
10	53
15	78
20	103

Identifying the Pattern

To model the data with a function, we need to identify the underlying pattern or relationship between the variables $j$ and $k$ . Upon examining the data, we notice that the values of $k$ increase by a certain amount as the values of $j$ increase by 5.

Calculating the Difference

To confirm our observation, let's calculate the difference between consecutive values of $k$ :

$j$	$k$	$\Delta k$
0	3	-
5	28	25
10	53	25
15	78	25
20	103	25

As expected, the difference between consecutive values of $k$ is constant at 25.

Modeling the Data

Based on our observation and calculation, we can model the data with a linear function of the form:

$k = 3 + 25j$

This function represents a straight line with a slope of 25 and a y-intercept of 3.

Verifying the Model

To verify our model, let's substitute the values of $j$ from the table into the function and calculate the corresponding values of $k$ :

$j$	$k$ (calculated)	$k$ (actual)
0	3	3
5	28	28
10	53	53
15	78	78
20	103	103

As expected, the calculated values of $k$ match the actual values.

Conclusion

In this article, we modeled the data provided in the table using a linear function. We identified the underlying pattern, calculated the difference between consecutive values of $k$ , and verified our model by substituting the values of $j$ into the function. This example demonstrates the importance of mathematical modeling in understanding and describing real-world data.
