Math Problem Statement

Graph the function g(x) = 5|x - 6| + 2 and describe its properties.

Solution

The graph shown represents the equation:

g(x)=5x6+2g(x) = 5 |x - 6| + 2

Let’s break this down step by step:


Understanding the Equation

  1. General Form: g(x)=axh+kg(x) = a |x - h| + k, where:

    • aa controls the slope (steepness).
    • (h,k)(h, k) is the vertex (the turning point of the graph).
    • The absolute value causes the "V" shape.
  2. Key Information:

    • a=5a = 5: This gives the slope of the two "arms" of the graph.
    • h=6h = 6 and k=2k = 2: The vertex of the graph is at (6,2)(6, 2).

Graph Characteristics

  1. Vertex:

    • The graph changes direction at the vertex (6,2)(6, 2).
  2. Slopes:

    • To the right of x=6x = 6, the slope is +5+5.
    • To the left of x=6x = 6, the slope is 5-5.
  3. Shape:

    • The "V" shape is symmetric about the vertical line x=6x = 6.

Analyzing the Graph

  • The graph begins at (6,2)(6, 2) and extends upward symmetrically.
  • The positive slope causes the right arm to increase steeply.
  • The negative slope creates the downward trend on the left arm.

Key Observations from the Graph

  • The green dot at (6,2)(6, 2) marks the vertex.
  • Both arms extend linearly with a steepness corresponding to 55.

Tip: To graph absolute value functions, always identify the vertex and the slopes of the arms. This ensures accuracy when sketching the "V" shape.
