The Table Shows a Function: Is It Linear or Nonlinear?

Understanding the Basics of Linear and Nonlinear Functions

In mathematics, a function is a relation between a set of inputs (called the domain) and a set of possible outputs (called the range). A function can be either linear or nonlinear, depending on its behavior. In this article, we will explore the characteristics of linear and nonlinear functions and determine whether the given table represents a linear or nonlinear function.

What Are Linear and Nonlinear Functions?

A linear function is a function that can be written in the form of a straight line, where the output changes at a constant rate with respect to the input. In other words, a linear function has a constant slope. The equation of a linear function is typically written in the form of y = mx + b, where m is the slope and b is the y-intercept.

On the other hand, a nonlinear function is a function that does not have a constant slope. Nonlinear functions can have a variety of shapes, including curves, bends, and even multiple peaks and valleys. Nonlinear functions are often represented by equations that involve powers, roots, or other non-linear operations.

Analyzing the Given Table

The given table shows a function with input values of x and corresponding output values of y. To determine whether this function is linear or nonlinear, we need to examine the relationship between the input and output values.

x	y
0	17
3	12
6	10

Calculating the Slope

One way to determine whether a function is linear or nonlinear is to calculate the slope between two points on the graph. If the slope is constant, then the function is likely linear. If the slope changes, then the function is likely nonlinear.

Let's calculate the slope between the first two points: (0, 17) and (3, 12).

Slope = (y2 - y1) / (x2 - x1) = (12 - 17) / (3 - 0) = -5 / 3 = -1.67

Now, let's calculate the slope between the second and third points: (3, 12) and (6, 10).

Slope = (y2 - y1) / (x2 - x1) = (10 - 12) / (6 - 3) = -2 / 3 = -0.67

As we can see, the slopes between the two pairs of points are different. This suggests that the function is not linear.

Conclusion

Based on the analysis of the given table, we can conclude that the function is nonlinear. The slopes between the two pairs of points are different, indicating that the function does not have a constant slope. Therefore, the correct answer is B. Nonlinear.

Key Takeaways

A linear function has a constant slope, while a nonlinear function does not.
To determine whether a function is linear or nonlinear, we can calculate the slope between two points on the graph.
If the slope is constant, then the function is likely linear. If the slope changes, then the function is likely nonlinear.

Real-World Applications

Understanding the difference between linear and nonlinear functions is crucial in various fields, including physics, engineering, economics, and computer science. Nonlinear functions are often used to model complex systems, such as population growth, chemical reactions, and electrical circuits. In contrast, linear functions are often used to model simple systems, such as straight-line motion and uniform acceleration.

Final Thoughts

In conclusion, the table shows a function that is nonlinear. The slopes between the two pairs of points are different, indicating that the function does not have a constant slope. This analysis highlights the importance of understanding the characteristics of linear and nonlinear functions in mathematics and their applications in various fields.
