Math Problem Statement

Use interval notation to indicate all real numbers between and including −2 and 8.

Solution

In interval notation, all real numbers between and including 2-2 and 88 are written as:

[2,8][-2, 8]

The square brackets indicate that the endpoints 2-2 and 88 are included in the interval.

Would you like more details or have any questions?


Here are some related questions to consider:

  1. How would the interval notation look if 2-2 were not included?
  2. What is the interval notation for all real numbers greater than 55?
  3. How do you represent an interval that includes all real numbers except zero?
  4. How would you write the interval for all numbers between 10-10 and 33, not including either endpoint?
  5. What is the notation for an interval that includes only one endpoint, such as x3x \geq -3 and x<6x < 6?

Tip: Remember that square brackets [][ ] indicate inclusivity of endpoints, while parentheses ()( ) show exclusion of endpoints.
