Absolute value functions are essential in mathematics, offering Which Graph Represents the Function p(x) = |x – 1|? insights into various real-world phenomena and mathematical principles. When dealing with absolute value functions, understanding their graphical representations is crucial. In this article, we’ll delve into the function p(p)=∣p–1∣p(x)=∣x–1∣ and explore how its graph behaves on the Cartesian plane.
Introduction to Absolute Value Functions
Absolute value functions are mathematical functions that express the distance of a number from zero on the number line Which Graph Represents the Function p(x) = |x – 1|?, disregarding its sign. They are denoted by ∣p∣∣x∣, where px represents any real number. These functions are fundamental in algebra, calculus, and other branches of mathematics.
Understanding the Function p(p)=∣p–1∣p(x)=∣x–1∣
Let’s dissect the function p(p)=∣p–1∣p(x)=∣x–1∣. Here, px is the input variable, and the expression ∣p–1∣∣x–1∣ represents the absolute value of px minus 1. This function computes the distance between px and 1 on the number line.
Interpreting the Graph of p(p)=∣p–1∣p(x)=∣x–1∣
When we graph p(p)=∣p–1∣p(x)=∣x–1∣, we observe a distinctive V-shaped curve centered at p=1x=1. The vertex of this graph occurs at the point (1, 0), representing the minimum value of the function. As px moves away from 1 in either direction, the function’s value increases linearly.
Key Characteristics of the Graph
One key characteristic of this graph is its slope. On the left side of the vertex (for p<1x<1), the slope of the graph is -1, indicating a downward slope. On the right side of the vertex (for p>1x>1), the slope becomes 1, showing an upward slope.
Graphical Transformation of Absolute Value Functions
Graphical transformations such as shifting, stretching, and reflecting can alter the appearance of absolute value function graphs. For example, shifting the graph of p(p)=∣p∣p(x)=∣x∣ horizontally by 1 unit to the right results in the graph of p(p)=∣p–1∣p(x)=∣x–1∣.
Comparing p(p)=∣p–1∣p(x)=∣x–1∣ with Other Absolute Value Functions
Contrasting p(p)=∣p–1∣p(x)=∣x–1∣ with similar functions like p(p)=∣p∣p(x)=∣x∣ or p(p)=∣p+1∣p(x)=∣x+1∣ reveals differences in vertex position and slope behavior. Understanding these distinctions aids in graph interpretation and problem-solving.
Real-Life Applications
Absolute value functions have practical applications in various fields such as physics, economics, and engineering. For instance, in physics, these functions can describe the magnitude of a particle’s displacement from a reference point over time Which Graph Represents the Function p(x) = |x – 1|?.
