If the Function Is One-To-One, List the Inverse Function by Switching

question 299

Multiple Choice

If the function is one-to-one, list the inverse function by switching coordinates or inputs and outputs.
- $$\mathrm { f } = \{ ( - 5,1 ) , ( - 1,5 ) , ( - 7 , - 7 ) , ( 7,7 ) \}$$

• A) \(f ^ { - 1 } = \{ ( 7 , - 7 ) , ( - 7 , - 1 ) , ( 1 , - 5 ) , ( - 7,7 ) \}\)
• B) \(\mathrm { f } ^ { - 1 } = \{ ( 1 , - 5 ) , ( 5 , - 1 ) , ( - 7 , - 7 ) , ( 7,7 ) \}\)
• C) \(f ^ { - 1 } = \{ ( 7 , - 7 ) , ( 5 , - 1 ) , ( 1 , - 1 ) , ( - 7,7 ) \}\)
• D) not one-to-one
