Problem
QUESTION 3 If the domain of a one-to-one function is $[-2,6]$ and its range is $[-8,10]$, what is the range of its inverse function? Write your answer as one interval without writing D or R or any other letters/symbols. Use inf for infinity. Do not put any spaces. Example: (-inf,5]
Solution
Step 1 ：The range of the inverse function of a one-to-one function is the same as the domain of the original function. Therefore, the range of the inverse function is \([-2,6]\).
Step 2 ：Final Answer: \(\boxed{[-2,6]}\)
