Answer: For us to find f-1(-2), we need to determine the value of the inverse function of f when the input is -2.
The inverse function f-1 "undoes" the original function f. It takes the output of f and returns the original input. In other words, if we have a value y and apply the function f to it, and then apply the inverse function f-1 to the result, we should get back the original value y.
However, without knowing the specific function f, we cannot determine the value of f-1(-2) in this case. The function f could be any function, and its inverse could have a different behavior. Therefore, we need more information about the function f in order to find the value of f-1(-2).
