Math Example: Absolute Value Functions: Example 12

Topic

Special Functions

Description

The image depicts a graph of the absolute value function y = |-5x + 4|. The graph opens upward and is narrower than y = |x|, with the vertex marked at (0.8, 0). This example illustrates how a negative coefficient with a larger absolute value and a constant inside the absolute value affect the graph's steepness and horizontal position. Absolute value functions are a fundamental concept in algebra, introducing students to equations that involve taking the absolute value of a variable or expression. This example showcases how changes in the equation impact the resulting graph's shape, steepness, and position. Providing multiple worked-out examples is essential for students to fully comprehend 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 negative coefficients with larger absolute values on the graph's steepness, and how constants inside the absolute value affect the function's horizontal position. Through repeated exposure to diverse examples, students can build intuition and improve their ability to analyze and graph absolute value functions independently.
