Answer

one-to-one-function inverse: $\{(6,3)(10,2),(12,5)\}$

Work Step by Step

The given set of ordered pairs, $ \{(3,6)(2,10),(5,12)\} $, has $y$-values that are unique. Hence, the function with the given set of ordered pairs is a one-to-one function. The inverse is derived by interchanging the $x$- and $y$-coordinates of every ordered pair. Hence, the inverse is $ \{(6,3)(10,2),(12,5)\} $.
