If the following defines a one-to-one function, find its inverse. If not, write "Not one-to-one."
-$\{(-2,4),(2,-4),(8,-2),(-8,2)\}$
A) $\{(4,-2),(-4,2),(-2,8),(2,-8)\}$
B) $\{(4,-2),(-4,2),(-2,-8),(2,8)\}$
C) Not one-to-one
D) $\{(4,-2),(-4,2),(8,-2),(2,-8)\}$

Quizplus · Accepted Answer

The given function is one-to-one because each domain value maps to a unique range value, and no range value is repeated. The inverse of a function swaps the positions of the elements in each ordered pair, making choice A the correct inverse.

If the Following Defines a One-To-One Function, Find Its Inverse {(−2,4),(2,−4),(8,−2),(−8,2)}\{(-2,4),(2,-4),(8,-2),(-8,2)\}{(−2,4),(2,−4),(8,−2),(−8,2)}

If the Following Defines a One-To-One Function, Find Its Inverse $\{(-2,4),(2,-4),(8,-2),(-8,2)\}$
