Which answer choice best describes the domain for this situation?
Understand the Problem
The question is asking which option best describes the domain of a certain situation, implying a mathematical context where different ranges of real numbers are being considered.
Answer
All real numbers greater than or equal to 0 and less than or equal to 100.
Answer for screen readers
The best choice is: All real numbers greater than or equal to 0 and less than or equal to 100.
Steps to Solve
-
Identify the Range of Numbers The problem is asking for a domain that describes a range of values. The options provided suggest different ranges based on real numbers.
-
Examine Each Option
- Option 1: All real numbers greater than 0 and less than 100: This indicates a range (0, 100).
- Option 2: All real numbers greater than 0 and less than 50: This indicates a smaller range (0, 50).
- Option 3: All real numbers greater than or equal to 0 and less than or equal to 100: This includes both endpoints, giving [0, 100].
- Option 4: All real numbers greater than or equal to 0 and less than or equal to 50: This includes both endpoints, giving [0, 50].
-
Compare Ranges for Clarity Determine which range covers the largest domain or fits best with the given scenario.
-
Select the Most Inclusive Option Since we need to find the broadest domain, the one that includes all real numbers from 0 to 100 is suitable.
The best choice is: All real numbers greater than or equal to 0 and less than or equal to 100.
More Information
This option encompasses the entire interval from 0 to 100, including both endpoints. It captures the largest set of values compared to the other options provided.
