If the following defines a one-to-one function, find its inverse. If not, write "Not one-to-one."
-$\{(9,-5),(13,6),(19,20)\}$
A) $\{(9,6),(9,13),(20,19)\}$
B) $\{(-5,9),(19,13),(20,6)\}$
C) $\{(-5,9),(6,13),(20,19)\}$
D) Not one-to-one

Quizplus · Accepted Answer

The function is one-to-one because each input has a unique output. The inverse is found by swapping the pairs, resulting in $\{(-5,9),(6,13),(20,19)\}$.

If the Following Defines a One-To-One Function, Find Its Inverse {(9,−5),(13,6),(19,20)}\{(9,-5),(13,6),(19,20)\}{(9,−5),(13,6),(19,20)}
