Question 462

Multiple Choice

Find the inverse of the function and state its domain and range .
- {(9,8) ,(7,7) ,(5,6) ,(3,5) }\{ ( 9 , - 8 ) , ( 7 , - 7 ) , ( 5 , - 6 ) , ( 3 , - 5 ) \}


A) {(7,8) ,(8,5) ,(9,7) ,(7,6) };D={(7,8,9};R={(8,57,6}\{ ( - 7 , - 8 ) , ( - 8,5 ) , ( 9,7 ) , ( - 7 , - 6 ) \} ; \mathrm { D } = \{ ( - 7 , - 8,9 \} ; \mathrm { R } = \{ ( - 8,57 , - 6 \}

B) {(8,9) ,(7,7) ,(6,5) ,(5,3) };D={8,7,6,5};R={9,7,5,3}\{ ( - 8,9 ) , ( - 7,7 ) , ( - 6,5 ) , ( - 5,3 ) \} ; \mathrm { D } = \{ - 8 , - 7 , - 6 , - 5 \} ; \mathrm { R } = \{ 9,7,5,3 \}

C) {(7,8) ,(5,5) ,(9,5) ,(7,6) };D={7,5,9};R={8,5,6}\{ ( - 7 , - 8 ) , ( - 5,5 ) , ( 9,5 ) , ( - 7 , - 6 ) \} ; \mathrm { D } = \{ - 7 , - 5,9 \} ; \mathrm { R } = \{ - 8,5 , - 6 \}

D) {(9,18) ,(7,17) ,(5,16) ,(3,15) };D={9,7,5,3},R={18,17,16,15}\left\{ \left( 9 , - \frac { 1 } { 8 } \right) , \left( 7 , - \frac { 1 } { 7 } \right) , \left( 5 , - \frac { 1 } { 6 } \right) , \left( 3 , - \frac { 1 } { 5 } \right) \right\} ; \mathrm { D } = \{ 9,7,5,3 \} , \mathrm { R } = \left\{ - \frac { 1 } { 8 } , - \frac { 1 } { 7 } , - \frac { 1 } { 6 } , - \frac { 1 } { 5 } \right\}
