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

question 95

Multiple Choice

If the function is one-to-one, list the inverse function by switching coordinates or inputs and outputs.
- $f = \{ ( - 9 , - 8 ) , ( 8,9 ) , ( 2,1 ) , ( - 2 , - 1 ) \}$

• A) not one-to-one
• B) \(f ^ { - 1 } = \{ ( - 8 , - 9 ) , ( 9,8 ) , ( 1,2 ) , ( - 1 , - 2 ) \}\)
• C) \(f ^ { - 1 } = \{ ( - 1,2 ) , ( 9,8 ) , ( - 8,8 ) , ( 1 , - 2 ) \}\)
• D) \(f ^ { - 1 } = \{ ( - 1,2 ) , ( 2,8 ) , ( - 8 , - 9 ) , ( 1 , - 2 ) \}\)

Definitions:

Van Der Waal Interactions

Weak attractions between molecules or parts of molecules that result from transient local partial charges.

Nonpolar Molecules

Molecules that do not possess distinct poles or charges, making them not easily soluble in water.

Attractive Forces

Forces that cause particles or objects to move toward one another, including gravitational, electromagnetic, and molecular interactions.

Transient Regions

Areas or phases that exist for a short duration, often changing rapidly in their properties or characteristics.
