If the function is one-to-one, list the inverse function by switching coordinates or inputs and outputs.
-$\mathrm { f } = \{ ( - 5,10 ) , ( - 14 , - 1 ) , ( 19,16 ) \}$
A) not one-to-one
B) $f ^ { - 1 } = \{ ( 10 , - 5 ) , ( - 1 , - 14 ) , ( 16,19 ) \}$
C) $f ^ { - 1 } = \{ ( 10 , - 5 ) , ( 19 , - 14 ) , ( 16 , - 1 ) \}$
D) $f ^ { - 1 } = \{ ( - 5 , - 1 ) , ( - 5 , - 14 ) , ( 16,19 ) \}$
