of variation.
-

• A) \(\mathrm { y } = - \frac { 16 } { \mathrm { x } ^ { - 2 } } ;\) Power \(= - 2 ;\) constant of variation \(= - 16\)
• B) \(y = - 16 x\); Power \(= 1\); constant of variation \(= - 16\)
• C) \(y = - \frac { 16 } { x }\); Power \(= - 1\); constant of variation \(= - 16\)
• D) \(\mathrm { y } = \frac { 16 } { \mathrm { x } ^ { 2 } } ;\) Power \(= - 3 ;\) constant of variation \(= 16\)
