If for a particular one-to-one function f(2) = 13, what are the corresponding input and output
maks197457 [2]

Answer:

f^{-1}(13) = 2.

Step-by-step explanation:

For function f, the notation f(2) = 13 means that when the input to the function is 2, the output would be 13.

The inverse function of a one-to-one function f is commonly denoted as \!f^{-1}.

The inverse function undoes the action of the original function. In this question, f maps 2 to 13. Thus, f^{-1} would need to map 13\! back to 2\!. Therefore, f^{-1}(13) = 2 should be the corresponding input and output values.
