Math Problem Statement

Which absolute value equation represents the graph shown?

Solution

To solve this, we need to analyze the graph and the options provided.

The graph shows two green dots at 12-12 and 4-4 on a number line, which indicates that these values are solutions of the absolute value equation.

The general form of an absolute value equation is:

xa=b|x - a| = b

Where aa is the central point (midpoint between the two solutions) and bb is the distance from aa to one of the solutions.

  1. Find the midpoint:

    • The two points are 12-12 and 4-4.
    • The midpoint is 12+(4)2=162=8\frac{-12 + (-4)}{2} = \frac{-16}{2} = -8.
  2. Find the distance:

    • The distance between 12-12 and 8-8 is 44, which is the value of bb.

Thus, the absolute value equation is:

x+8=4|x + 8| = 4

The correct answer is the option x+8=4|x + 8| = 4.

Would you like more details or have any questions?

Related questions:

  1. What are other examples of absolute value equations with different midpoints?
  2. How do we determine the solutions to an absolute value equation like x+8=4|x + 8| = 4?
  3. What happens if the distance between the two points is greater than 4?
  4. Can you explain the geometric meaning of an absolute value function on a number line?
  5. How do we solve an absolute value equation when the absolute value is equal to zero?

Tip:

Always remember that the absolute value represents the distance from a central point, so finding the midpoint is a key step to constructing the equation.
