To determine who is correct about the range of the function, we need to analyze the function itself. However, since the function is not explicitly provided in your message, I can only explain the concept of range and how to determine which sets of numbers (-10, 0, 4, 5, 7) belong to it.
Definition of Range: The range of a function is the set of all possible output values (y-values) that the function can produce, given its domain (x-values). In simpler terms, it’s the set of numbers that can be generated by plugging the input values into the function.
Steps to Identify the Range:
-
Analyze the function: If you have the mathematical expression of the function (for example, f(x) = x², f(x) = 2x + 3, etc.), you can substitute different values of x to find corresponding f(x) values.
-
Identify all output values: Evaluate the function across the interval relevant to its domain and collect all distinct outputs.
-
Check the values in question: Specifically examine:
- Stephen's claim about numbers: -10, 0, 4, and 7.
- Mary's claim concerning -10, 0, 4, and 5.
-
Compare results: Determine which of the numbers from Stephen's or Mary's list are found in the range obtained from your analysis of the function.
Without the specific form of the function, I can't definitively state who is correct. However, follow these steps with the actual function to find the range, and then check the claims made by Stephen and Mary against the range to conclude. If you can provide the function, I can help you analyze it directly.
