If the function is one-to-one, find its inverse. If not, write "not one-to-one."
-$$\{ ( 3 , - 5 ) , ( 5 , - 3 ) , ( 9,2 ) , ( - 9 , - 2 ) \}$$
A) $\{ ( - 2,9 ) , ( 9,5 ) , ( - 5,3 ) , ( 2 , - 9 ) \}$
B) not one-to-one
C) $\{ ( - 5,3 ) , ( - 3,5 ) , ( 2,9 ) , ( - 2 , - 9 ) \}$
D) $\{ ( - 2,9 ) , ( - 3,5 ) , ( - 5,5 ) , ( 2 , - 9 ) \}$

Quizplus · Accepted Answer

A function is one-to-one if each x-value maps to a unique y-value, and vice versa. The given function meets this criterion, so its inverse can be found by swapping each pair's x and y values. Option C correctly lists the swapped pairs.

If the Function Is One-To-One, Find Its Inverse {(3,−5),(5,−3),(9,2),(−9,−2)}\{ ( 3 , - 5 ) , ( 5 , - 3 ) , ( 9,2 ) , ( - 9 , - 2 ) \}{(3,−5),(5,−3),(9,2),(−9,−2)}

If the Function Is One-To-One, Find Its Inverse $\{ ( 3 , - 5 ) , ( 5 , - 3 ) , ( 9,2 ) , ( - 9 , - 2 ) \}$
