Answer:
Explanation:
The domain of a relation refers to the set of all possible input values. Let's analyze each option to determine its domain:
1. "All real numbers greater than or equal to 0": In this case, the domain includes all numbers starting from 0 and going to positive infinity. The set would be written as [0, ∞).
2. "All real numbers": This option represents the entire set of real numbers, including positive, negative, and zero.
3. "All real numbers between -6 and 4": In this case, the domain consists of all numbers that are greater than -6 and less than 4, but not including -6 or 4. The set would be written as (-6, 4).
4. "All real numbers greater than -2": Here, the domain includes all numbers greater than -2. The set would be written as (-2, ∞).
To summarize:
- Option 1: Domain = [0, ∞)
- Option 2: Domain = (-∞, ∞)
- Option 3: Domain = (-6, 4)
- Option 4: Domain = (-2, ∞)
Remember, the domain represents the valid input values for the relation.
