Introduction
In mathematics, particularly in algebra and graph theory, understanding the concept of vertical translations is crucial for analyzing and interpreting the behavior of functions. A vertical translation is a transformation that shifts the graph of a function up or down by a specified number of units. In this article, we will explore the concept of vertical translations, focusing on the specific case where the graph of $g(x)$ is a vertical translation of the graph of $f(x)$.
What is a Vertical Translation?
A vertical translation is a transformation that shifts the graph of a function up or down by a specified number of units. This type of transformation does not change the shape or size of the graph, but rather its position on the coordinate plane. In other words, a vertical translation moves the graph of a function up or down, without affecting its horizontal position.
The Graph of $g(x) = f(x) - 3$
Given the equation $g(x) = f(x) - 3$, we can analyze the graph of $g(x)$ in relation to the graph of $f(x)$. The equation $g(x) = f(x) - 3$ indicates that the graph of $g(x)$ is a vertical translation of the graph of $f(x)$.
Vertical Translation: Up or Down?
To determine whether the graph of $g(x)$ is a vertical translation up or down, we need to examine the equation $g(x) = f(x) - 3$. The term $-3$ in the equation indicates that the graph of $g(x)$ is shifted down by 3 units from the graph of $f(x)$. This is because subtracting a positive number from a function value results in a downward shift.
Conclusion
In conclusion, the graph of $g(x) = f(x) - 3$ is a vertical translation of the graph of $f(x)$ down 3 units. This type of transformation is essential in understanding the behavior of functions and their graphs.
