Description
This math example illustrates the creation of a table of x-y coordinates and the corresponding graph for the absolute value function y = |2x + 1| - 1. The image shows a V-shaped graph with points at (-2, 2), (-1, 0), (0, 0), (1, 2), and (2, 4). This example is part of a series exploring absolute value functions, demonstrating how combining a coefficient greater than 1, a constant inside the absolute value, and subtracting a constant outside affects the graph's steepness and position. Absolute value functions are an important concept in algebra, introducing students to equations that involve taking the absolute value of a variable or expression. This collection of examples showcases various forms of absolute value functions, allowing students to observe how changes in the equation impact the resulting graph's shape, steepness, and orientation. Providing multiple worked-out examples is crucial for students to fully grasp the concept of absolute value functions. By examining different scenarios, students can identify patterns and develop a deeper understanding of how these functions behave. This approach helps reinforce important concepts such as the characteristic V-shape of absolute value graphs, the impact of coefficients greater than 1 on the graph's steepness, how constants inside the absolute value affect the horizontal position, and how constants outside the absolute value influence the vertical position. Through repeated exposure to diverse examples, students can build intuition and improve their ability to analyze and graph absolute value functions independently.
