Oct 13, 2025 by talynt.org 46 views

The given function is $g(x) = 2 \llbracket \frac{x}{3} \rrbracket$ , where $\llbracket x \rrbracket$ represents the greatest integer less than or equal to $x$ . This function can be interpreted as a step function, where each step has a height of 2 units and a width of 3 units.

Visualizing the Graph

To visualize the graph of this function, we can start by plotting the points where the function changes its value. These points occur at $x = 3, 6, 9, 12, ...$ . At each of these points, the function value jumps up by 2 units.

Length of Individual Line Segments

To find the length of the individual line segments of this function, we need to consider the distance between each pair of consecutive points. Since the function has a constant slope of 2/3 between each pair of points, the length of each line segment can be calculated as follows:

The length of the first line segment (from $x = 0$ to $x = 3$ ) is given by $\frac{2}{3} \cdot 3 = 2$ .
The length of the second line segment (from $x = 3$ to $x = 6$ ) is given by $\frac{2}{3} \cdot 3 = 2$ .
The length of the third line segment (from $x = 6$ to $x = 9$ ) is given by $\frac{2}{3} \cdot 3 = 2$ .
This pattern continues for each subsequent line segment.

Positive Vertical Separation Between Each Line Segment

To find the positive vertical separation between each line segment, we need to consider the difference in function values between each pair of consecutive points. Since the function value jumps up by 2 units at each point, the positive vertical separation between each line segment is given by 2 units.

Simplifying the Answer

In summary, the length of each individual line segment of the function $g(x) = 2 \llbracket \frac{x}{3} \rrbracket$ is 2 units, and the positive vertical separation between each line segment is 2 units.

Conclusion

In this article, we have analyzed the function $g(x) = 2 \llbracket \frac{x}{3} \rrbracket$ and found the length of its individual line segments and the positive vertical separation between each line segment. The results show that each line segment has a length of 2 units and a positive vertical separation of 2 units. This analysis provides a deeper understanding of the function's behavior and its graphical representation.

Key Takeaways

The function $g(x) = 2 \llbracket \frac{x}{3} \rrbracket$ is a step function with a height of 2 units and a width of 3 units.
The length of each individual line segment of the function is 2 units.
The positive vertical separation between each line segment is 2 units.

Further Analysis

This analysis can be extended to other step functions with different heights and widths. By understanding the behavior of these functions, we can gain insights into their graphical representation and mathematical properties.
