Math Problem Statement
Solution
We are given the function with the domain , and we need to find its range.
Step 1: Find the values of at the endpoints of the domain.
-
At : So, when .
-
At (not included, but needed to find the boundary): So, as approaches 5 from the left.
Step 2: Determine the range.
The function is a linear function with a negative slope, meaning it decreases as increases. Therefore, as ranges from to just below 5, ranges from to just above .
Hence, the range of is:
Thus, the correct answer is the second option: .
