===========================================================

In the world of mathematics, accuracy and precision are paramount. When it comes to describing the relationship between two variables, a well-defined function is essential. In this article, we will delve into the claim made by Thabo regarding the function illustrated in the table. Specifically, we will examine whether the formula $y = 5x + 10$ accurately represents the relationship between the variables $x$ and $y$.

Understanding the Table

---

The table provided by Thabo contains five data points, each representing a unique value of $x$ and the corresponding value of $y$. The table is as follows:

$x$	1	2	3	4	6
$y$	15	10	5	0	-10

Thabo's Claim

---

Thabo asserts that the formula $y = 5x + 10$ accurately represents the relationship between the variables $x$ and $y$. To evaluate this claim, we need to determine whether the formula correctly predicts the values of $y$ for each value of $x$ in the table.

Analyzing the Formula

---

The formula $y = 5x + 10$ is a linear function, which means that it can be represented by a straight line. To analyze this formula, we can start by plugging in the values of $x$ from the table and calculating the corresponding values of $y$.

Calculating $y$ Values

---

Let's calculate the values of $y$ for each value of $x$ using the formula $y = 5x + 10$.

$x$	$y = 5x + 10$
1	$5(1) + 10 = 15$
2	$5(2) + 10 = 20$
3	$5(3) + 10 = 25$
4	$5(4) + 10 = 30$
6	$5(6) + 10 = 40$

Comparing Calculated Values with Table Values

---

Now that we have calculated the values of $y$ for each value of $x$, we can compare these values with the corresponding values in the table.

$x$	Calculated $y$	Table $y$
1	15	15
2	20	10
3	25	5
4	30	0
6	40	-10

Evaluating Thabo's Claim

---

Based on the calculations and comparisons above, we can see that the formula $y = 5x + 10$ does not accurately represent the relationship between the variables $x$ and $y$. The calculated values of $y$ do not match the corresponding values in the table for all data points.

Conclusion

---

In conclusion, Thabo's claim that the formula $y = 5x + $ accurately represents the relationship between the variables $x$ and $y$ is incorrect. The formula does not correctly predict the values of $y$ for each value of $x$ in the table. Therefore, we must reject Thabo's claim and seek a more accurate function to describe the relationship between $x$ and $y$.

Future Directions

---

In the future, we can use various methods to determine the correct function that describes the relationship between $x$ and $y$. Some possible approaches include:

• Linear Regression: We can use linear regression to find the best-fitting line that represents the relationship between $x$ and $y$.
• Polynomial Regression: We can use polynomial regression to find the best-fitting polynomial that represents the relationship between $x$ and $y$.
• Non-Linear Regression: We can use non-linear regression to find the best-fitting non-linear function that represents the relationship between $x$ and $y$.

By exploring these alternative approaches, we can gain a deeper understanding of the relationship between $x$ and $y$ and develop a more accurate function to describe this relationship.

In conclusion, Thabo's claim that the formula $y = 5x + 10$ accurately represents the relationship between the variables $x$ and $y$ is incorrect. The formula does not correctly predict the values of $y$ for each value of $x$ in the table. Therefore, we must reject Thabo's claim and seek a more accurate function to describe the relationship between $x$ and $y$. By exploring alternative approaches, we can develop a more accurate function to describe this relationship and gain a deeper understanding of the underlying mathematical principles.
