question 70

Multiple Choice

Find the second derivative of the function.
- $$y = \frac { x ^ { 4 } + 9 } { x ^ { 2 } }$$

• A) \(\frac { d ^ { 2 } y } { d x ^ { 2 } } = 2 + \frac { 54 } { x ^ { 4 } }\)
• B) \(\frac { d ^ { 2 } y } { d x ^ { 2 } } = 2 - \frac { 54 } { x ^ { 4 } }\)
• C) \(\frac { \mathrm { d } ^ { 2 } \mathrm { y } } { \mathrm { dx } ^ { 2 } } = 2 \mathrm { x } - \frac { 18 } { \mathrm { x } ^ { 3 } }\)
• D) \(\frac { \mathrm { d } ^ { 2 } \mathrm { y } } { \mathrm { dx } \mathrm { x } ^ { 2 } } = 1 + \frac { 54 } { \mathrm { x } ^ { 4 } }\)
