question 75

Multiple Choice

Determine whether the function is one-to-one. If it is one-to-one find an equation or a set of ordered pairs that defines
the inverse function of the given function.
- $$f = \{ ( 0,0 ) , ( 1,5 ) , ( - 2,10 ) \}$$

• A) one-to-one; \(\mathrm { f } ^ { - 1 } = \{ ( 0,0 ) , ( 5 , - 2 ) , ( 10,1 ) \}\)
• B) one-to-one; \(\mathrm { f } ^ { - 1 } = \left\{ ( 0,0 ) , \left( 1 , \frac { 1 } { 5 } \right) , \left( - 2 , \frac { 1 } { 10 } \right) \right\}\)
• C) one-to-one; \(\mathrm { f } ^ { - 1 } = \{ ( 0,0 ) , ( 5,1 ) , ( 10 , - 2 ) \}\)
• D) not one-to-one
