To find the inverse of a function, you swap the x and y values in each ordered pair. The given function is one-to-one because each x-value maps to a unique y-value, and vice versa. Thus, the inverse is $\{ ( - 4 , - 19 ) , ( - 12,7 ) , ( - 1,16 ) \}$.

If the Function Is One-To-One, Find Its Inverse {(−19,−4),(7,−12),(16,−1)}\{ ( - 19 , - 4 ) , ( 7 , - 12 ) , ( 16 , - 1 ) \}{(−19,−4),(7,−12),(16,−1)}

If the Function Is One-To-One, Find Its Inverse $\{ ( - 19 , - 4 ) , ( 7 , - 12 ) , ( 16 , - 1 ) \}$
