Math Problem Statement

write the absolute value inequality

Write the absolute value inequality for the given number line graph.

Solution

To write the absolute value inequality for the graph on this number line, we need to examine the range of values shown. Here’s the breakdown:

  1. The black dots at 4-4 and 44 represent endpoints, indicating the interval between them.
  2. The shading extends in both directions from 10-10 to 1010, which suggests that the values are between 10-10 and 1010.
  3. Since the shading includes the range between these two points, this suggests an absolute value inequality.

Constructing the Inequality

The graph shows values that are less than or equal to 1010 in distance from 00, which we can express with absolute value notation: x10|x| \leq 10

This inequality states that xx can range from 10-10 to 1010, including both endpoints.

Here are 5 related questions for further exploration:

  1. How would the inequality change if the shading went only up to 99 instead of 1010?
  2. What would the graph look like if the inequality were x<10|x| < 10?
  3. How would you write an absolute value inequality for the range [5,5][-5, 5]?
  4. Can you explain the concept of absolute value in terms of distance on a number line?
  5. What is the difference between xa|x| \leq a and x<a|x| < a on a number line?

Tip: Absolute value inequalities like xa|x| \leq a represent all points within a distance aa from 00, which translates visually to an interval on the number line.
